Blue-Green Deployment Strategies for PCF Microservices

Blue-green deployment is a well-known pattern for updating software components by switching between simultaneously available environments or services. The context in which a blue-green deployment strategy is used can vary from switching between data centers, web servers in a single data center, or microservices in a Pivotal Cloud Foundry (PCF) deployment. In a microservices architecture, […]

Best Practices for Instrumenting Containers with AppDynamics Agents

In this blog I will show some best practices for instrumenting Docker containers, using docker-compose with a few popular AppDynamics application agent types. The goal here is to avoid rebuilding your application containers in the event of an agent upgrade, or having to hard-code AppDynamics configuration into your container images. In my role as a […]

Deploying AppDynamics Agents to OpenShift Using Init Containers

There are several ways to instrument an application on OpenShift with an AppDynamics application agent. The most straightforward way is to embed the agent into the main application image. (For more on this topic, read my blog Monitoring Kubernetes and OpenShift with AppDynamics.) Let’s consider a Node.js app. All you need to do is to add […]

How Top Investment Banks Accelerate Transaction Time and Avoid Performance Bottlenecks

A complex series of interactions must take place for an investment bank to process a single trade. From the moment it’s placed by a buyer, an order is received by front-office traders and passed through to middle- and back-office systems that conduct risk management checks, matchmaking, clearing and settlement. Then the buyer receives the securities […]
