Chaos Engineering

How reliability differs between monolithic and microservice-based architectures

Microservices have forever changed the way we build applications. Tools like Docker and Kubernetes made microservice-based architectures widely accessible to software developers, and cloud platforms like Amazon EKS made deploying containers fast and inexpensive. They've also enabled even small engineering teams to deploy code faster, leverage fault tolerance and redundancy, scale more efficiently, and take full ownership of their services from development all the way into production.

How to run Chaos Engineering experiments in your CI/CD pipeline

Part of the Gremlin Office Hours series: A monthly deep dive with Gremlin experts. Ad-hoc Chaos Engineering experiments are great for learning more about how your systems work, but they don’t tell you how your systems behave over time. As new features get deployed, environments change, and regressions get introduced, even the most resilient systems can gain reliability risks. QA and performance testing are already built into CI/CD - why not reliability?

How to build zone-redundant cloud instances and clusters

Redundancy is a core tenet of cloud computing. While major cloud platforms have high targets for reliability, they can still fail, and it’s important for teams to have a plan for when they do. But how can you build services that can withstand something as disruptive as a datacenter outage? In this blog, we’ll show you how to prepare for availability zone outages by proactively detecting services operating in a single zone.

Five ways Gremlin helps organizations meet DORA requirements

Enacted by the European Union, the Digital Operational Resilience Act (DORA) establishes new standards for digital operational resilience in the financial sector. DORA changes the financial sector's approach to digital security and resilience by imposing stringent Information and Communication Technology (ICT) risk management, incident reporting, third-party risk management, and regular testing.

Three roles you need for reliability success

It’s one thing to say that reliability is a priority for your organization, and a whole other thing to make actual, demonstrable improvements in the availability of your applications. Sadly, it’s common for organizations to invest time, money, and effort into improving reliability only to barely nudge the needle on incidents and downtime. But there are hundreds of companies successfully improving their reliability posture—and doing it at enterprise scale.

How to build reliable services with unreliable dependencies

In an earlier blog, we looked at slow dependencies and how they can impact the reliability of other services. While we explored what happens when dependencies are degraded, what happens when dependencies outright fail? What can you do when your application or service sends a request to another service, and nothing comes back? We’ll answer this question by using Gremlin to proactively test a service with multiple dependencies.

Confident Cloud Migrations How a Top 5 Bank Ensured Reliability With AWS and Gremlin

In today's competitive landscape, migrating to the cloud brings substantial benefits, but the cloud’s new architectures and tools also bring new reliability risks and considerations. The challenge: Enterprises have to figure out how to capitalize on the benefits of the cloud while ensuring a seamless, reliable transition. This webinar offers a look at how to provide application reliability before, during, and after migrations with AWS and Gremlin.

Building Resilience in the Cloud With the AWS Well Architected Framework and Gremlin

Reliability and resilience in the cloud requires a different approach. Thankfully, the AWS Well-Architected Framework is a proven blueprint for cloud architects and engineering leaders seeking to design and operate resilient systems on AWS.

How to make your services resilient to slow dependencies

When discussing reliability, we tend to focus on the things that we have control over: applications, virtual machine instances, deployment patterns, etc. But this ignores a significant and ever-growing part of nearly all modern software: dependencies. Dependencies are services that provide extra functionality for other services and applications. For instance, many websites depend on databases, caches, payment processors, and similar services in order to function.

Hitting reliability goals in the face of layoffs

It’s never easy when layoffs hit your organization. In addition to the personal impact of losing friends and coworkers from your team, those who remain are left trying to achieve the same business goals with less people and resources. Unfortunately, layoffs and restructuring have become a common part of business. But you’re not alone. Your partners (including Gremlin) are here to help you navigate your new reality.
