When I started working at Purple managing the E-commerce stack, I inherited a single AWS EC2 instance that represented our entire infrastructure. The problem was, the company was doubling in size every few months, and with this exponential increase in load combined with the issues we were already experiencing with this infrastructure, it became a large business risk.
Amazon DocumentDB is a managed MongoDB-compatible database service provided by AWS. It provides the database in clusters, with multiple instances, for high-availablity. To help with cost-reduction strategies, AWS allows DocumentDB clusters to be stopped and restarted. While the cluster is stopped, you’re not charged. So it’s a great candidate to shut off overnight and on weekends if it’s not needed.
OpenStack has been around for a good while now, and many of us associate it with the period of IT technology’s initial transition from individual appliance implementation on hardware, to cloud compute and virtualisation. And yet in 2020 we cannot skip this topic when talking telco infrastructure. So how is OpenStack still pertinent to telco organisations, and what in broad terms is new and exciting or worth discussing today about OpenStack?
When we talk about going Cloud-Native we often think about Microservices as well, probably because that’s where the actual innovation, time, cost-saving, and better utilization of resources happen. And CloudHedge is keenly focused on helping enterprises to bring the benefits of containers to traditional legacy business applications that are run on a widely used operating system: AIX!
Since 2018, Watchdog has provided automatic, machine learning-based anomaly detection to notify you of performance issues in your applications. Earlier this year, Watchdog started grouping APM anomalies across your services, allowing you to better understand the scope of the issue.
As an IT specialist, you should have an aptitude for all the essential tools vital for the efficient running of IT infrastructure. These software programs designed for their specific purposes basically serve the same purpose as an engineer’s toolkit. They make it easy to get the job done, and on top of that, get it done well. Depending on your job, you may or may not need to use all the tools. But as an IT professional, you should know which tool can help you with which task.
With HAProxy, you can implement a circuit breaker to protect services from widespread failure. Martin Fowler, who is famous for being one of the Gang of Four authors who wrote Design Patterns: Elements of Reusable Object-Oriented Software, hosts a website where he catalogues software design patterns. He defines the Circuit Breaker pattern like this: The basic idea behind the circuit breaker is very simple. You wrap a protected function call in a circuit breaker object, which monitors for failures.
