Accordingly, the remaining 27% of clusters are self-managed by the customer on cloud virtual machines. Of the organizations in the Kubernetes survey, 71% run databases and caches in Kubernetes, representing a +48% year-over-year increase. Messaging : RabbitMQ and Kafka are the two main messaging and event streaming systems used.

I wrote this post on MyRocks because I believe it is the most interesting new MySQL storage engine to have appeared over the last few years. The use case is the TPC-C benchmark but executed not on a high-end server but on a lower-spec virtual machine that is I/O limited like for example, with AWS EBS volumes.

An important concept was to simulate database users called Virtual Users in parallel (rather than concurrently) to accurately simulate a real database workload with multiple users running from separate systems. Cached vs Scaled Workloads. The workload also outputted the data from the Virtual Users by simulating individual terminals.

Given its unchanging nature, static content is ideal for caching. Yes, these might change based on localization settings, but in terms of storage, it’s still a completely baked cookie that the server can choose to serve or not serve.Whenever a user clicks on an episode, these bits remain unchanged.

Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. Redundancy is also critical for disaster recovery.

Consider an example where a company is running multiple virtual machines (VMs) on a cloud provider. Whether you're scaling storage solutions like S3 buckets, compute resources like EKS clusters, or content delivery mechanisms via CDNs, Terraform offers a streamlined approach.Â â€For CDNs, redundancy is really important.

In my previous blog posts, I highlighted the importance of using Event Sequence as the sort key. Some of the feedback has been that sorting can be a cumbersome operation because: Using sys.fn_xe_file_target_read_file the XML has to be queried and indexed which can take time and space, followed by the order by event sequence query.
