Today, I'm happy to announce that the AWS EU (Paris) Region, our 18th technology infrastructure Region globally, is now generally available for use by customers worldwide. With this launch, AWS now provides 49 Availability Zones, with another 12 Availability Zones and four Regions in Bahrain, Hong Kong, Sweden, and a second AWS GovCloud (US) Region expected to come online by early 2019.

Not too long ago I had written about creating an API with Node.js and Express that accepted image uploads and manipulated the images to be Android compliant before returning them in a ZIP archive. This article was titled, Create an Android Launcher Icon Generator RESTful API with Node.js, and Jimp , and it was a great example of creating APIs that that did most of their work in memory.

A process to build RESTful APIs that solve users’ needs with simplicity, reliability, and performance. Every piece of software exists to solve a real-world problem. Directly or indirectly. Most web APIs are consumed by client applications running on PCs, mobile devices, etc., which in turn are used by humans. Despite being consumed directly by machines, APIs are made to satisfy the needs of human beings, so designing them should follow a user-centered process, but often it doesn’t.

The Mars Climate Orbiter was a robotic space probe manufactured by Lockheed Martin and launched by NASA’s JPL on December 11, 1998. The purpose of this probe was to study the Mars climate, atmosphere, and surface changes and to act as the communications relay in the Mars Surveyor '98 program for Mars Polar Lander. The total cost of this mission was $327.6 million.

How companies can use ideas from mass production to create business with data. Strategically, IT doesn't matter.

Learn how to properly design RESTful APIs communication with clients, accounting for request structure, authentication, and caching. This series of articles shows you how to derive an easy-to-use, robust, efficient API to serve users on the web or on mobile devices. We are using the principles of RESTful architecture over HTTP. In the first piece, we started from a list of specs for a simple bike rental service, defining URLs and the HTTP methods to serve the app.

NativeScript is great. There is an easy setup process (at least for Windows, I unfortunately don’t have a Mac so I can’t speak on the MacOS side of things) that provides an executable that helps you through all the steps of setup. Unfortunately, like any automated setup process, things can go awry and stop your excitement on starting on your native apps with some errors that have little suggestion on how to move forward.

Regardless of what project management software you use, be it JIRA, Asana, Trello, or whatnot, one thing is true for all of them: adding new tasks is really easy. Finishing things requires actually doing the work or coming up with an extremely compelling reason to delete a task. The notion of tasks being easy to create and hard to remove will naturally result in many tasks piling up.

Load testing is a form of non-functional testing that is carried out to understand the behaviour of an application under a specific user load. A load test is done by simulating the real time user load on the application under test, and this determines how the application responds when multiple users hit the server simultaneously and it reveals the application’s response time, CPU and memory usage, network and bandwidth usage.

My last talk for 2017 was at AWS re:Invent, on "How Netflix Tunes EC2 Instances for Performance," an updated version of my [2014] talk.

A simple framework for implementing message-based, user-initiated CRUD operations. A message-based microservices architecture offers many advantages, making solutions easier to scale and expand with new services. The asynchronous nature of interservice interactions inherent to this architecture, however, poses challenges for user-initiated actions such as create-read-update-delete (CRUD) requests on an object.

Many developers have one of two opinions about unit tests: they believe 100% of the code has to be covered by unit tests, or they believe 100% of the code has to be covered by unit tests but they have reasons for not writing any. It isn’t common to find people who dislike the idea of unit tests. The main cost of having unit tests is spending time to write them.

It’s a large open plan area with several connected zones, kitchen, patio, dining area, living area, with lots of light bulbs and far too many light switches. Upgrading all the bulbs to something like Philips Hue didn’t look like the right way to go, there are too many bulbs so it would be expensive, and we’d need to keep the light switche

For stack scalability, elasticity at the business logic layer should be matched with elasticity at the caching layer. Ever increasing numbers of people are using mobile and web apps and the average time consumed using them continues to grow. This use comes with expectations of real-time response, even during peak access times. ? Modern, cloud-native applications have to stand up to all this application demand.

I was recently working on a Functions as a Service (FaaS) project using AWS Lambda and Node.js. However, I was running into an issue where my package dependencies found in my node_modules directory were for the wrong platform once deployed to Lambda. This is not the first time I experienced a problem like this. I knew the issue straight away because I encountered the same thing when trying to use a node_modules directory generated on Mac from a Windows computer.

When you’re developing an Android mobile application, it is critical that you come up with a nice launcher icon for all possible Android screen densities. If you’re not too familiar with Android, there are mdpi , hdpi , xhdpi , xxhdpi , and xxxhdpi densities as of now. This number could change in the future. Once you’ve got your icon, resampling or resizing it for each possible screen density can become a pain in the butt.
