Serverless technologies are lowering the barrier to entry for global deployments with on-demand pricing and scaling. AWS’ serverless offerings are now supported in 16 regions, and with the help of Up Pro’s latest v1.2.0 release we’re going to take a look at setting up a globally distributed app to decrease latency for your customers.

If you look around the Serverless Application Repository console, you will find a number of applications that can help you ship logs from CloudWatch Logs to external services. One such example is the LogzioCloudWatchShipper application below.

Cutting-edge serverless technologies and old-school mainframes have more in common than you'd think: Each can be a black box that blocks deep insights.

With AWS Lambda, we get blue-green deployment out of the box. After we update our code, requests against our function would be routed to the new version. The platform would then automatically dispose of all containers running the old code to free up resources.

Serverless computing is a cloud-based application architecture where the application’s infrastructure and support services layer is completely abstracted from the software layer. Any computer program needs hardware to run on, so serverless applications are not really “serverless” - they do run on servers - it’s just that the servers are not exposed as physical or virtual machines to the developer running the code.

Like any other creation in progress or in the making, serverless applications, need to be tested and monitored. How else would you know if what you’ve created is providing desired results? Before putting your “newborn child” out into the world, you must make sure that it’s ready for the world. Software or even hardware of any sort will first be tested before it goes to mass production, and the same goes for your serverless applications.

AWS Lambda has a soft limit of 75GB for deployment packages for all your functions (including the layers you use). This might seem a lot, but a team that has fully embraced serverless can reach this limit very quickly.

I am a proud lazy programmer. This means that if I can automate a task, I will absolutely do it. Especially if it means I can avoid doing the same thing more than once. Luckily, as an engineer, my laziness is an asset - because this week, it led me to write an HTML scraper for our Changelog, just so I wouldn’t have to manually update the Changelog feed on our new app homepage (btw, have you seen our new app homepage? It’s pretty sweet).

I’m going to be biased in this post and it’s going to be ok because all the information you’re about to see are 100% correct and fair towards both services.

With AWS Lambda, we can deploy and scale individual functions. However, we as engineers still like to think in terms of services and maintain a mapping between business capabilities and service boundaries. The service level abstraction makes it easier for us to reason about large systems. As such, cohesive functions that work together to serve a business feature are grouped together and deployed as a unit (i.e. a service) through CloudFormation.
