From YouTube: 2016 Beijing node live-Jose Miguel Parrella-End to end Node.js app development in the cloud: Azure

Description

Jose Miguel Parrella is an Open Source Product Manager with the Microsoft Azure team. He’s had over 15 years of experience in the field of open source ranging from policy and advocacy to consulting and Linux systems integration. He joined Microsoft in 2010 as an open source strategist in Latin America and the Caribbean.

In this talk, we'll explore common architectures and considerations for cloud Node.js deployments based on learnings from customers running Node.js in Microsoft Azure. The session includes a number of demos and discussion on deployment architectures and patterns (for example, VM Scale Sets, containers, PaaS, etc.) and using cloud solutions from Node.js like managed databases or IoT telemetry/data streaming facilities. This is also a great opportunity for participants to learn about the approach to open source developers are taking in the public cloud.

A

Joseph apologizing years reckon some toe tag: let's go hwy, 17, verse or another chest put on black pepper, ok to.

B

Try a new school all right knee how either one thank you very much for spending your Saturday afternoon with me and talking about nodejs I. Think that's really tight!.

C

haha Fish on concealer to an uncle you wanna, since I San Antonio, the dealership well like do LTR all three less.

B

So I'll try this. Would you ever say what should I may walk.

A

B

She, when Audrina, then hey shiv, Angela, whoa long so Microsoft I'm, sorry.

B

Open source is one of the things I'm most passionate about today, I'm here to share some of the learnings that we have from developers using nodejs in the cloud. That's going to be the agenda today, the.

C

Teacher little better, not do you kinda, I associated fatality, 39, I, gough and selfish retirement. One woman's operation ojs fun games. Here, too yeah the tickets. You may now features what you know me that usually into our neighborhood.

B

At Microsoft we've been in this open-source journey for over a decade we have this Heinlein show some of the most I think important things we have done in this space. It has been very difficult. It is very difficult to change Microsoft, especially if you are an open-source enthusiast, but it's not impossible. So then ever let anyone tell you that any anything is impossible. And now, if you see here, we have no Jas.

B

It seemed like yesterday when we brought nodejs to windows with the community, but today we have such a fantastic, no JSTOR that I'm sharing with you today.

C

Digital, not addition. We have found national dishes on union ave rock island to go to go to me all the in gear lets you. Should you be a good all-around, a run, she's um easier to and sing she say, town kannada now you'll see the morn. You should say camera only be high in effect. So no one now try the tiny, 10 yahoo faithful a rather go to the don t, see where outreach are focusing god, oh my god, ljs tomorrow, baculum LJ. Although windows, do you worry enough?

C

Till haha I should have fashions activity with him. I think.

B

You said it better, yes, thank you, so this is just one way to think about what the cloud offers to developers and what we doing a sure you can develop with whatever tools you need. You want, whatever pro mean languages, you use in frameworks, whatever tools you're using doesn't matter. If your developer, your data, scientist you're in operations, you can do it on the infrastructure, using virtual machines using containers, you can do it on the platform using many different things, including server, bless functions that we recently announced in preview. Well,.

C

Misshapen some jiggity abilities to cali sad yo, more agile, the UK, ok, fine ring and lunch will not please no dawdling from Canon signature watches on 0 sure sugar talking hi, now put it for them, which is all up in public order. You to go to cosi idea, 30 Mario Ponzo committee went on to a drone and you don't have a folder, so she the John Dorian the beautification, so that we have that your function, yogini, you don't eat you from what you see on the cast.

B

So what happens when we bring all those features to 30 places different places in the world? Well, you get a lot of people using this, and developers are really excited about all the things we're doing with open source. In a sure today, twenty-five percent of Asher is Linux or an open source programming language. Like note, and of course we have thousands of websites running note, thousands of note applications and many customers, I'm here to share with you no.

C

Omocha yeah tombaugh solo connect. Another day on tioman salir y section, one gave a small college now Kaiba under jay the car Sheriff a time job that you live in time. The shootin shell, naturally Sylvan Trina those are outside linux, photo shoots. You have a kind of the palm gamma beam from ljs, not even know who I sure your woman. We know that know that I dig our family now you're 300 or no 18. You look at a friends yeah one.

B

Of the customers have want to share with you today is merely merely is an interactive whiteboard from Argentina, and it's offered as a solution, nearly one hundred percent nodejs and they use MongoDB for the database and they then run anything on the X. Everything is on past now.

A

B

Why they do this is because they can get new customers. Actually, they have 350,000 new customers after they stole their note application in the cloud 1000 new users per day, and it's also very fast. They can deploy 20 times per they just very few seconds.

C

Genealogy is not even close. Una shall I 17 that you guys also murali the concert on islands in the TC luxury hotels, audio portion, ipad, Randy, NT, fool, domina, titre I should buy them too bad. She only jack the pass chamomile job de la bienvenida solution. Now, Allah knowledge is not sure everybody to go show your true who knows mongodb, not much more magic apples latina. She relaxes on social vertical know that your honor, how many will come around sundown sweet, I'm, fine, well solution, our son Timmy years on a magnet in luck.

C

She seems only tell me: do a poor man's ability or emotionally atrocious HR means he end up it. Don't roll not come back to weigh on how to negotiate? You can't let you see our team no English with you come to oakley. What's an ablution so.

B

Performance and agility are just two of the things we hear from our customers when they talk about nodejs, they like that javascript is pretty much everywhere. They like the community and obviously that means things like MDM and they like that they can use it for many different things. You know seven years ago. They think there would be JavaScript IOT and today we have no ideas on things. So that's very significant, and there are many interesting things that you can do with node.js today and.

C

Even on clothes on the phone, you know just answer it so make sure that you're down here, which is Sigma highly, should have a job working for philippines. You see another shooter drama, coming into our your little gesture to leave a job charles scribner sure to provide. Are you not turn to collect from the very knowledge, as you can take a cart or not to show you got to go feed on how to show to you when I come to the tertiary? Learn p.m.

C

no puncture, now tition ojs, now a cha'aka Japanese here link me feel so lethargic I. Ok, the dreamers in here, hey tellin, y'all, sounds I all here to believe we know your travel, it's even harsher cause. Yall sell it for myself. Thank you that email, no Jess, you.

B

Can even do some crazy things like this that I'm going to share with you two years ago, I helped the University of Washington set up an oj s, application into plow to monitor sis meek software and hardware that they had installed. Stay like that. Yes,.

C

C

Gender diversity, how about you we are going to take my personal fashion, good passer, now sheriff I know you have no chance that it'll Union, just bloody Nora to your merchandising cones, I see at hula digger, make sugar and chill today will be no Tom. What our entourage at home, watching indian garments in a function of she's here, Jim Cole, so.

B

In America they played this crazy sport of football and American football and people on the stadium yell so loud that they actually generated a little earthquake that was detected by this system and people at their homes in their inner Latin or laptops order. Phones could see that something happened in the stadium before the TV show day.

C

There are less useful, even as a community when you know he's not signal. No Jane Fonda even show me the Jeremy go around so tie down totally chance. El amor, the television show each other move on. You sure do go to corner pizza, but Vienna for a property. Knowledge of it is actually helium or lie to you at all. Do you know that kind of would be sad if I cash, you don't see any utility ensure your corner. Should one technology? Are you time, selfie, mother, DJ and.

B

Now, they're using that technology to create a earthquake detection system that we don't have in the US. But it's something very important for them and they're using no GS. Without so.

C

You know just home to value Germany gonna make what every turn back into the tensile she'll come back. How do you even care such as a signal? Not bad ptolemaic? Did you got eaten the gemstones evil, but.

B

When I talked to know developers about all the good things that they can do, it know they also tell me they have challenges, especially in the cloud. So here are some of the things they share with us. They want this to be very easy to deploy. They want to reduce the time between Cody and deployed. They want to make it easy game and they want to go beyond just flowing that step now.

B

In a sure, we have many different things I'm going to share with you fun experiments, so you can learn a little bit more about this, but easy deployment. Easy scale easy to do more are some of the things that.

C

Yahwah how the teachers are you know, I feel know that I olesya countdown to also deal in a seminar Jack be not too sure from social. The future yeah there you go yeoman see come to see how that's when we get home. Now, if you see a time a little shootie animal, also that they are an initiative of we walk, don't go high, schooler Johnny will project didn't, have the RTO, the mother and I OT son you to receive an animal at home or know them so can do that Johnny's a shitty! Definitely that yeah!

C

That's only cuz you're John Belushi thing in the jack cheese yeah. So.

B

I have a Raspberry Pi connected there, and I want to have a little application just showing some data. I would normally do this with a mean stack, BM in a sure, I can go to market place. I can search for mean I'll find one provided by a vid nami. That's a large company that sells this Linux stats and I can just deploy it and it will work great if I have one brother pie and one user. The application actually will look a little bit like this.

B

A

B

On top, and then some fields for things here and what's happening right now, is that the raspberry pi is going to start standing is just putting up it's going to start sending some data to the cloud. Nine.

C

Yo yo consul de ja vu s, TR.

B

Bho, you know what.

C

You get now Raspberry Pi now with Samuel attend church, a meeting he was having on Township glossary undulata chose, you know. Is it now? Do you know SRAM chawla without google that you have been spared the biggest GT right so fortunate ocean tsunami? Talking on the trigger gimmicks that you can start the whole na na na hote rigan reporting, so you ruined our sure you can either until you got a spare part. Oh you go.

C

You know who the water to go to tell until riff acknowledges that I don't do job without filter that filters, your plow selling say some quantity, traditional, the Raspberry Pi, not the occasion for us on Twitter, but.

B

There are going to be many challenges for an application like this to grow. If you have many raspberry PI's and many users and things get more complicated and you start thinking about Hughes, you start thinking about a batch processing. You start thinking about auto scaling and at some point you also start thinking about BMS scale, ambience and scaling all the other components of a solution. You.

C

Don't do the Union entire you should eat high of a usual for the 200 ml and deduction rule will do entirely sure. Well, go back to the show on the 20 become a fan or me or call me 3d and recommend here for me all copy that you can. It was also don't bother you, but I, don't know photos you see that you wrote on me I what I don't know. Okay,.

B

So normally you would scale this application by doing something like this splitting your data tier in your application here and then scaling depending on how many, the raspberry PI's or how many users you have.

C

Cantos garantizado coroner fasho denied when you're an awesome girl now monitor tompa tomba jilla. Xu jie zhang et need a job. You don't full song. Yo ho enterica, auto shop, I was pari. Passu shooting, I knew.

B

It was not a good idea to shut down the raspberry pi.

C

Bonding on your Raspberry Pi denied, so tell me action at issue pertaining to.

B

C

B

This microphone, jamba well I, usually throw that a cheer and I'll do the good.

C

In the back, ellora show boy.

B

Thing all right good, maybe you had some point, decide that you're going to use BMS for your front end for your application, so you're going to use pass, that's another way. You can also scale the application Oh.

C

Darla more efficient in there and you go to I think, do attend on NE, PP and I shown that will she see Michael and pass.

B

It's probably the time in the Raspberry Pi, but here's the solution that a one solution you can use in the cloud you can use cues. It's very inexpensive, it's great for things like telemetry, the type of scenario that we have and especially it's got a database. So you don't need a database administrator. I. Think developers are happy sometimes when they hear that.

C

You're gonna ruin your annuals and religion is shipped AHK volunteering, the sheer under an emotional cues. They don't even go after the tumba. Our God I did no tea. No sugar faso know so that y'all can see new from the book. Come enjoy our work for you, honey even have a rant about you, I, don't you cannot see you on the.

B

Other part of the solution is that you normally need to process all this information, but you're not going to create a new vm. For that we have something called functions. This is serverless. You need to create an operating system. You don't need to create a virtual machine. You just give your code and a trigger so anytime. The Raspberry Pi send some data to the cube. The function gets the data and then they can process it.

C

Now, how do they decide to look into I? Don't think either you know prefer even come on, then. She also since usually gets how to do it in order to be in Seattle till you, vm New Jersey, an artificial function: oh no, no Clara function, Natasha Suren, establish your routine official total isidro army and is here usually all know to the tomb of your mind. Now he said I'm a good trigger virtual fancy. It your Raspberry Pi, like a clean back to assure you, you are fastened. Edges are cute round you, the kuna, go.

C

You know, functions.

B

Look like this, you can access them in the browser. You can also use git and your preferred tool. You can use javascript in many other languages, but seriously is there anything else other than JavaScript, and so you just write your code here and then you can find the input and output of your application. In this case, for example, I have a trigger from cuse, but you can have many different things like databases, blob storage, CDN and many others.

C

Member jennie now within a function is even Roger. She was an attractive young general function on google, mighty chilly new, cleaner Susie suure, the character to the community tiburon identity to appear not a function. I change, Sydney for the delay, PP sure 00 t go to troll. You cannot open, create some hearing on the shuttle yoga trigger wrongful, not to order yo planetary governor, but she nodded of japan. Tokyo station should be cooler how come to iowa city and in.

B

This case, my function is just putting.

A

B

Data, it's free is, if it's above average or red, if its fellow acknowledged.

A

C

In our charity, God function, bakunano, usually answer like that. Your shoe to the gelatine change in drinking usual, please idea garlic and ginger consumer guide out ginger. You.

B

Can put the in my case and put in the results back on a cube, but you can put in many different data repositories as well and.

A

B

Application that you have many options you can use spouse. You can use VMs, but I'm going to show you a special type of vm. You can use containers, I'm also going to share with you specific type of container technology. We have new cloud.

C

Tsunami to tragedy of ok fact without heels we can you pay from without the pool, so it's literally no utility the fantasia p.m. they should pass the Acacia container gzn. Oh ok, gotcha, g02 da jugaad yeah. I use a container reason here.

B

I'm using something called vm scale sit it's something we have in a sure where you don't have to think about the VMS anymore. If you're like me, you create a VM and you put it a name, and then you always think of your little baby. Little the end by its name, vm scale, sets put numbers on VMS and you no longer care about the specific vm.

B

So you have to describe everything on our template, including the instructions to get your application there, but once you do that, then the cloud takes care of it for you ultra.

C

Knowledge upon the sheet into the function of non-union around you can't read: English PT in the city. Cheaper means it.

A

Is a conservative, a sahaja no means a young piece.

C

You got to rank okok juanita national seashore I, don't show a little bit to kabhi and till four years legitimately me also. Neither do you know asha eagle, GT now and Rwanda Shinawatra. Not only is it je viens visit the gallery go through all about me into it, see what I told you down this year. Don't you know sure what is it Mia in.

B

This particular example I'm telling my template. You saw the visualization on the roster until the template that it has to use the nodejs image that is published by dynamic. That means that I don't even need to worry about getting no install, getting npn stole and all the tools that I need for my application. I just put it on the template and tell the vm scales it to employer.

C

Tarragona usual, no one knew that Oh children are also looking at 10 feet high or should not get na me the job in an odious. The degree image, GTA I know so that you know someone's here, I'm gonna, open totally flat once.

B

It's deployed it looks like this. This is a 2, VN scale, city and I'm, going to be able to change that, I'm going to show you and it's already running, and it has no Jas and all the other information for the scale said, including IP addresses this names. This sizes, the cloud took care of that, for me, I just had to tell it I want to know DJ svm see my scale said, and it reminds the instructions for my application and it went away it delivered. So he.

C

Got Ichiro mucho I'm to home now that it's an all-cash, it means anything kind of it. On my 18, how to the note is shitty hello, Jane, Chiana Jonah. Well, she had no Jay has come to a skill set with also the IP Mimi. Now for the job. There you go. Can't you get a pass out. I, don't shoot so don't mind to order. I have.

B

A load balancer that is created automatically and it's doing the load balancing of my web application. It already the text if the application is down for whatever reason and it takes that server out of the rotation. So it's very convenient then I can manage it from the portal. I can manage it from the API. This is just the tool I could use for a get post. I can believe, restore, do everything from here from the web interface or from the API, from whatever language you're, using or just talking straight to the API. So.

C

You're not tied to the way what aliquots forgot to come cheap either. For that reason, why, but is here in PP not have the java.util drug patents? You don't should clearly made you a fool, so it's it. Ok, so I know what I can do that RJ go beyond the Keynesian Angada and you consider bar take some of the jealousy on the show where I you saw. That is, it wondering could, even if he is a poop on Apollo and I, think it won't be. The one in about okay holds the dream to restore them.

C

No reserve the.

B

Result is that the application that's here, I can reload it. I can use it for many different devices, and it's it's. It has the scale step behind it. I don't have to worry I have to right now, but if I have more users than I can have more and I no longer have to worry about the pie, because I have q's and those cues are very inexpensive and they can scale for whatever I need. It doesn't matter how many devices I have and then on the front end. I also have the problem solved as well.

C

So you're not happy follow let's mosey on back to see the union. I think what would you dance in the show me that your sugar some job even the sword, you see those without the school salary corner eating, bouncing order to show how to butte on the water. You even got some gianna. Now, let's go natalia. I never wanted. You know: she'll be controlled, raspberry, pi, Jewish without Sundiata, well, location, own home and garden tools. Now, actually I can. Generally you gonna show me around calm down. You should be on how I told.

B

You that the ants on scales that don't have names, I'm just going to show that to you just ssh into one of those VMS, and it has this very weird number that was auto assigned by the cloud, and I can see my application is actually here, but it does. It doesn't make a lot of sense to you to actually look at that, because it's going to have this vm had just stopped right now and you won't get started. I sure will control it sure.

C

You know another car now it's a skill, Saturday don't reveal avicii about you, know hashanah p.m. comments. You should not do. Mel means the gym or not evening. Actual quits it'll be Karma. Chilling effect on see. You are John, you go calcutta, you I, didn't think I'm I sure. Did you go to vm a little sympathy, but now I know before you talk about cheating me honey. Oh dear, the.

B

Rbm also has a.

C

Number so they're just the same exactly.

B

The same DN, but just for capacity, and they have just different hello.

C

Come on Julia, vm deadly, you know, she's, you don't you that have a capacity, meow travel experience. You have both a little young now.

B

If I go to the API and I wanted to change, my I can just make a request to the API endpoint. Just change capacity and making kind and just send up to the cloud I will build provision three deviants for me with my own money.

C

Collison up without api api shall do capacity the job there you go to until time to Latoya you see: okay, okay, that'd be idea about you got another guy tongue. Oh say that y'all without a little funny, but I don't know forget watching, has seen them someone yep. So.

B

You also see this little box and the two things on the bottom. I told you I'm using to use, but this is not cues. This is just a regular comment box. This is actually mom Dody me, but MongoDB is not installed in this VMS.

B

The feature I'm using here is the feature that we have currently preview is support for mongodb on document DV document DB is a no sequel storage that microsoft offers in the cloud and started this februari. We have MongoDB wire protocol support. That means that you can just point your application. Your mean stack application to document EV and you convert it into a dean-stark application.

B

C

Param hans peter eckrich, the date on which others you do try having a portion of MongoDB shushanna should only do you live. I travel to the document agree with DB, don't wanna the DB nah she actually, the bouncy cottage are you? Girls really! No need for immediate are acting are a concussion of communication.

C

Well, the station teacher now mom will give me the dig, a well traveled over to the city in to shoot a young man. You should own warning. So that means that, but had to appoint immunity means that generally thought. You know how to teach em to children. So.

B

The final solution has q's to talk with the Raspberry Pi functions. To do all the things that I need to do without necessarily having to spin up a new vm document. The need for document needs, not everything is telemetry or logs. I can also do many other things with MongoDB supporting document unique and then, whatever choice of deployment for my application, I want, it can be passed scale sets is what I showed you today, and it can also be containers and I'm going to show you how that could look like in the second, no.

C

There are so many actors out there opportunity in your family or not trojan cache of a Raspberry Pi common audio cues, the Cincinnati tsunami artists, young Archie, elution, a giant I will be ending syllable new function to the fool, I all descended the range I'm gonna show you before she's, even from the sincere to the city, normal document DP, the one thing that have new tradition around things, work and initiative. I have easily enough to hold an idea to the skills that you don't pass. General appeal a charge and she's happier than she can tangle.

C

B

What I have here is a JSON file that is referring to a container image that is available in darker hub and is saying that this image is going to expose the port or 3000, and it's also saying that I need some specific CPU and memory for this image. But this is not going to be a vm. This is going to be a container, and this is not going to be a regular docker container. It's actually going to be managed by a product called V cos created by mesosphere. That's a part of Microsoft the.

C

Another chic oj silverdale of firing ovens here that I think I'm not believe on our shooter Dean. Tell me the doctor about you. Look thoughtful there to a poor children, constancy and shauna m yahoo. Did a container into the evening to the dealer teacher contend interior units, the traditional true devotee, rehana, Super, Bowl vehicle hoods, a little factor we cross the vehicle evening.

B

So what you have here is the e cos web interface, and it's showing me my cluster I have some memories on cpu. Some of that has been allocated because they have deployed my application, but you can see exactly how much capacity you have left in your cluster here. You don't even have to worry about the ends. You don't even have to think about them. Dcos will create more will make sure that your containers go where you have spare capacity and will orchestrate the North not only containers but also many meet data solutions as well.

C

Okay kind of jittery VCOs to give value to the tyranny and web interface. So in our territory, Kate hang the T to the division bar. He remains on cpu, a chocobo sure. If you not prefer someone easier to the reality version miss Philpot. They happily pendulum to know bcos the dealer they are in touch. You know it's often delicious. How could you wanna, you know, be taking part in Giles? You have except a few so.

B

Just like in the yen scales that scenario I can.

A

Just go to scale a mutation here.

B

And I can just this number five and then PCOS will schedule whatever it is they and eats for this to run five instances of the same application, so we should see memory being allocated as well as you have. The application gets yojana.

C

Don't obey cos to the skill sandra donna, buona noche de go shootin now homie cos education vampire. Now that you know I owner should be zero logical, surely the only way don't buy. Some point remains, but nice, if you listen, you are not familiar with you.

B

So containers are other option that you have if you want to deploy your node application to the cloud and I encourage you to look at the COS as one of the tools that you can use to ensure that all your VMs are being used. You are not paying more than what you need, because this is one of the challenges in your father and, as you can see, my five EMS are not running, so it's also very cool.

B

You can use many ways to provision the VMS I'm using a script, but you can use check you can use github deployments. You can use jenkins, you could use. There are many different tools you can use to provision mems your application in videos, so.

C

No Daria value, not knowledge, either 80 people from one container to 20 feet, haha jello, shots la comodidad, adagio, VCOs, tengo, Kawana country, giovanni tocci, military unfounded. Initially, as you like to fulfill okay, felony that'll take the show occasions a little spring. That's why your patient, Chad cats get popped in it. Thank you. Hopefully,.

B

The demo was fun, I wanted to share with you a little bit of what we see would know jazz in the cloud. What our customers and developers are saying, and some of the challenges and the solutions that we see as more people create great applications with node.js I wanted to make sure we have time for questions due today. So if you have any question, please let me know, though,.

C

As you well know, what so the JC, a tributary I've shown that I should read a nice enough, not sure your child or burned a documents examiner sure cousin adultery is the Chimera. You and say you don't have to accommodate an old in iana I. Don't rely the time the EC it even harder. Okay Lisa to define not even how I'll teach others about 20 knots and I'm, not sure human action.

B

C

B

Because you're in a later killin.

C

B

It is Saturday afternoon, sir.

C

Toby was young I, see.

A

The total 16 have it just off. Ok,.
