HammerDB is a software application for database benchmarking. It enables the user to measure database performance and make comparative judgements about database hardware and software. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking.

Among the different components of modern software solutions, the database is one of the most critical. Regardless of whether the computing platform to be evaluated is on-prem, containerized, virtualized, or in the cloud, it is crucial to consider several essential factors.

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?

This is because AWS Lambda provides a relatively low barrier for entry into cloud computing without the need to pursue a whole lift-and-shift operation right away. When using Lambda, you might soon end up using more serverless offerings, like databases, which makes emulating the same environment locally even harder.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. top(1) showed that only the Cassandra database was consuming CPU. We ended up setting it in the BaseAMI for all cloud services.

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.

They came up with a horizontally scalable NoSQL database. Instead of relational (SQL) databases defined primarily through a hierarchy of related sets via tables and columns, their non-relational structure used a system of collections and documents. The effects have hit cloud vendors who can’t possibly compete with MongoDB.

One of the nice things about using public cloud is the ability to use pre-canned application virtual appliances created by companies like Bitnami. We can use these same appliance images on Nutanix AHV to easily do a Postgres database benchmark. Get the bitnami image. wget [link]. qemu-img convert *vmdk bitnami.qcow2.

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. I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R.

From HammerDB version 3.2 there is an additional interface that enables HammerDB to run as Web Service. Using a browser to navigate to that port will show the help screen.
