I am often asked by customers, vendors or internal teams to explain CPU capacity planning for large production databases running on VMware vSphere.

In summary there are a few simple best practices to follow for sizing CPU for large production databases:

  • Plan for one vCPU per physical CPU core.
  • Consider NUMA and ideally size VMs to keep CPU and memory local to a NUMA node.
  • Right-size virtual machines. Add vCPUs only when needed.

Generally this leads to a couple of common questions:

Hi,

I would like to know if anyone has had some experience in building systems for multiple end-users.

To keep things simple, in a hypothetical example, say an Event Booking System, where a Venue could sign up to use such a system and define it's Venue, costs, calendars, etc.. and then invite their customers to book the Venue on different days/times.

If I wish to offer such a system to many Venues, there are a number of options available.

I am looking for a way to deploy production changes (code and/or production configs) via script or some other systematic way other than the Ensemble/Deploy page in the Management Portal. My goal is to store these configurations in Subversion, then have a piece that can pull the XML from source control and deploy it to a given server. Is there some kind of script that I can run on a given server to perform this deployment? If so, I can tie it up with Subversion using another tool that I have access to.

Hey Developers,

We're pleased to invite you to join the next InterSystems IRIS 2020.1 Tech Talk: DevOps on June 2nd at 10:00 AM EDT!

In this InterSystems IRIS 2020.1 Tech Talk, we focus on DevOps. We'll talk about InterSystems System Alerting and Monitoring, which offers unified cluster monitoring in a single pane for all your InterSystems IRIS instances. It is built on Prometheus and Grafana, two of the most respected open source offerings available.

Next, we'll dive into the InterSystems Kubernetes Operator, a special controller for Kubernetes that streamlines InterSystems IRIS deployments and management. It's the easiest way to deploy an InterSystems IRIS cluster on-prem or in the Cloud, and we'll show how you can configure mirroring, ECP, sharding and compute nodes, and automate it all.

Finally, we'll discuss how to speed test InterSystems IRIS using the open source Ingestion Speed Test. This tool is available on InterSystems Open Exchange for your own testing and benchmarking.

Hello,

I work on deploying IRIS inside Docker container. I really like %Installer class can automate many steps. I want to establish an ECP connection to a mirror database and then define a remote database on the application server. I have already seen we can create local database and namespace in %Installer. What code is needed to establish ECP connection?

The following post outlines an architectural design of intermediate complexity for DeepSee. As in the previous example, this implementation includes separate databases for storing the DeepSee cache, DeepSee implementation and settings. This post introduces two new databases: the first to store the globals needed for synchronization, the second to store fact tables and indices.

Hi, Community!

I'm using Git with DeepSee and when I need to do a commit to the git repo I'm exporting ALL the pivots and dashboards from the namespace. But I can forget to do that) And it can take time for a large system.

What is the way to manage automatical export of DeepSee artefacts which we are editing in UI (Cubes, Pivots, Dashboards, Pivot Variables, Term lists, Shared Measures) into files every time when I push Save button?

Access to IRIS from Rust

What do you think If I will say you, that very soon you will be able to connect to IRIS from the application written in Rust.

What is Rust

Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency. Rust is syntactically similar to C++, but can guarantee memory safety by using a borrow checker to validate references. Rust achieves memory safety without garbage collection, and reference counting is optional. (c) Wikipedia

IRIS Runtime Environment

Hello community.

I have project on IRIS.

I am trying to make application deployable.

The Idea is to have 1 file that customer can download and run. For now I realize that whole intersysytems developer kit that includes Studio, terminal acts as runtime environment (Like Java has JDK).

Is it possible to wrap my project to 1 archive (Back to Java example .war or .jar) and run it on some application server (like Tomcat) without Studio etc..?

Thank you!

Just got the new beta version of Docker, with depreciation warning of AUFS. It's so bad news when InterSystems does not support used by default storage driver overlay2. Recently I thought to play with Google Kubernetes Engine, and realized that I can't work with InterSystems products there due to incompatibility with Storage Driver. Maybe it's already time to think about support?

Container configuration management

If you're deploying to more than one environment/region/cloud/customer, you will inevitably encounter the issue of configuration management.

While all (or just several) of your deployments can share the same source code, some parts, such as configuration (settings, passwords) differ from deployment to deployment and must be managed somehow.

In this article, I will try to offer several tips on that topic. This article talks mainly about container deployments.
