When using Lambda, you might soon end up using more serverless offerings, like databases, which makes emulating the same environment locally even harder. In consideration of this reality, The Dynatrace Lambda monitoring extension supports all well-known IaC technologies to deploy Dynatrace along with your function.

Unfortunately, container security is much more difficult to achieve than security for more traditional compute platforms, such as virtual machines or bare metal hosts. Many good security tools provide that function, and benchmarks from the Center for Internet Security (CIS) are clear and prescriptive. Why is container security tricky?

When you list the HammerDB directory you can now see a directory called “scripts” This directory contains CLI scripts to build, run, delete and query TPROC-C and TPROC-H workloads against all databases. If HammerDB is running on a separate system from the database under test then you should modify this value accordingly.

In this example, we will use the CLI to run TPROC-C on a MariaDB database to illustrate the concepts. This way is typically the fastest way to determine the maximum throughput of a database with minimal configuration, and over time has been proven to show the same performance ratios between systems as a well configured fixed throughput setup.

Estimates vary, but most reports put the average cost of unplanned database downtime at approximately $300,000 to $500,000 per hour, or $5,000 to $8,000 per minute. With so much at stake, database high availability and fault tolerance have become must-have items, but many companies just aren’t certain which one they must have.

HammerDB Variable or Step Workloads are an advanced testing feature that enables you to automatically vary the load on the database over a period of time. When taking this approach you would not focus on the test result but instead monitor the databases ability to cope with the variation in demand and transaction response times.

Another big jump, but now it was my job to run benchmarks in the lab, and write white papers that explained the new products to the world, as they were launched.

Similarly for this guide MySQL can be swapped for a mySQL based databases such as MariaDB. As is also the case this limitation is at the database level (especially the storage engine) rather than the hardware level. As is exactly the same with PostgreSQL for system choice a 2 socket system is optimal for MySQL OLTP performance.
