Keeping in mind the dynamic DevOps culture in our company and others, we set out to streamline our development pipelines using a modern container-based approach. Our goal was to empower developers to have the flexibility and ease of adapting the pipeline to their development methodologies while providing more time for development and testing rather than spending time on creating and maintaining CI/CD pipelines. Developers can easily on-board their solutions without spending too much time learning about the underlying technology that drives the pipeline.

Containers, Kubernetes and Health Checks for the Win! With the massive adoption of containers, many large enterprises as well as startups embracing containers in their application architecture patterns. With this huge growth, we have new challenges to monitor 1000’s of containers running in 10’s and 100’s of Container Platforms such as Kubernetes. There are many APM (Application Performance Management) products that provide end to end monitoring of application services. However, it can be complicated to build dashboards to get simple status of these services.

Motivation As we have talked about in an earlier post, Chaos Engineering is a method by which the stability of complicated cloud infrastructures can be assessed and validated. The current Chaos Engineering tools do not support application-specific attacks, but rather vm-specific attacks. Now, this works if each application is on its own VM, but a lot of our applications are deployed in Cloud Foundry which moves apps without the developers even needing to know what VM their container is running on.

Reliable, maintainable test automation, delivered by anyone. Continuous Delivery drives towards faster time to market which in turns demands new code to be tested and verified at high speed. For many years, QA and development teams have leveraged test automation tools to allow more tests to be run in a shorter amount of time. However, some teams may not have enough runway to build test automation “SDET” skillsets to meet demanding release timeline.

Why I wrote Orchestration Desk? Hello everybody !! I will be writing my first tech blog today. The topic I will be covering is “why I wrote a open source module ‘Orchestration-Desk’” (https://github.com/tmobile/orchestration-desk/wiki) along with one of my favorite topic “Feature Toggles”. Feature toggles are very popular among software industry /teams that wants continuous development and release of software products. The teams want the ability to show/hide features on demand.

Purpose: To control an alarm using a Raspberry Pi and Python At T-Mobile, our development teams run pipelines to build, test, and deploy our code. Any disruption in the pipeline means new code can’t be delivered, so fixing pipeline issues when they arise becomes top priority. To emphasize the importance of having an “always on” pipeline, we wanted a way to alert the teams explicitly, rather than just notifications via email/chat, when there’s a failure in the job pipeline.

Gartner predicts that “through 2020, 95 percent of cloud security failures will be the customer’s fault.” The very nature of public cloud, the ease at which developers can create, modify and delete resources –gives us the agility we love but also makes it easy to overlook security guidelines. The dynamic nature of the cloud further complicates matters, especially if you have a very large footprint. From a recent survey conducted by cybersecurity-insiders.

It was one year ago today (on my birthday) that T-Mobile publicly embraced the open source community with the release of Jazz — a framework to unlock the full potential of serverless computing. It was both the start of a new journey for T-Mobile and a significant milestone along a path that we have been on for the past two and a half years: from telco to technology company. So, I think now is a great time to reflect on the progress we made over the last year…

Overview At T-Mobile, we have been making a large push toward cloud infrastructures. Through this process, we have been taking large monoliths from the past and breaking them into a series of microservices. This allows us to easily scale parts of services which are overloaded with requests and to increase the redundancy of our systems by having backups ready to go in the event one of them crashes or the hosting hardware has issues.

Introducing Project Casquatch At T-Mobile, we have been rapidly developing new applications on top of a micro-service architecture through a combination of Java and Cassandra, including all the latest and greatest technologies. This is great except that Cassandra pushes a significant amount of the performance tuning and high availability configuration from the database layer up to the application layer. This leads to a few problems for the enterpise as all these policies are individually implemented (or not) by each service and database availability is now out of central control, leaving each developer to implement as they see fit.

T-Mobile is transforming wireless, and the public cloud is a key enabler of that transformation. This week, technologists from around the world are gathering in Las Vegas for re:Invent, a conference for Amazon Web Services and the public cloud. As one of the largest tech events of the year, it’s a great venue for the Un-carrier to showcase the innovative development work we are doing. Here are the great stories being presented by T-Mobilers this week–be sure to check out the webcasts!

As the Un-carrier, T-Mobile is transforming wireless. Technology and software development play a key role in enabling that transformation. We work every day on technology to make systems more robust while enabling faster delivery at reduced cost–all so we can provide more value to our customers! Today we are making available as open source, both large and small projects that contribute to that effort: Jazz Jazz is being developed by T-Mobile’s Cloud Center of Excellence to make it easier to develop, deploy and operate solutions, shifting workloads from VMs and IaaS to serverless and container platforms.
