Tutorial Update: ElastiCache in WordPress

 |  Post a comment

Like everything else, platforms move with the times, and AWS is no exception. This tutorial is an update of a previous post in our blog on Elasticache with Wordpress. We’ve re-edited it to reflect some important changes made by Amazon Web Services since publishing the original post.

What is Elasticache and why use it?

ElastiCache is a service provided by Amazon Web Services that allows you to prepare a cluster of nodes to execute Memcached, a memory cache system that is much faster than standard disc options. It reduces the heavy load of your application on EC2 instances by following a principle of not doing the same job more than once: after generating content for the first time, this content is saved in the memory and then used to respond to the next requests more rapidly. This means that your users receive content faster, and by reducing the load, your front-end can handle more requests than before.

Spot Instances uncovered

Recently we deconstructed the rocket science behind AWS Instance Reservation. Now it’s time to delve deeper into Spot Instances.

AWS Log analytics with Spot Instances

End-of-quarter data analysis, batch scientific calculation … These are tasks that require high machine utilization but only for short, specific periods of time. In the old, on-premise data center world, executing this type of task would require major expenditure on hardware that would then lie dormant the rest of the year.
And in the Cloud? Architecting for the cloud means architecting for cost efficiency. AWS Spot Instances are a great solution for performing periodic, workload-intense or interruption-tolerant tasks while keeping resource expenses in tow.
