About

Analog Devices (ADI) defines innovation and excellence in signal processing. Based in Massachusetts, Analog is a publicly listed company operating in 30 countries with 125,000 customers who are using one or more of their 45,000 different product SKUs. ADI specializes in integrated circuits (analog, mixed-signal and digital signal processing) that play a fundamental role in converting, conditioning and processing real-world phenomena such as light, sound, temperature, motion and pressure into electrical signals used in a wide array of electronic equipment.

Situation

Analog needed to upgrade their website to the latest version of the Sitecore content management system and move the application hosting platform to a Platform-as-a-Service (PaaS) cloud-based infrastructure on Microsoft Azure. The move of the Sitecore application platform to Azure also required a SaaS or Managed Solr service in the cloud.

This transition to SearchStax Cloud allows ADI to have full control on the application stack without managing the underlying infrastructure and automatically scale up or down based on website traffic or resource contention needs. 

Solution

ADI had very complex business requirements and they needed their highly trafficked website to be operational nearly 100% of the time. In addition, their requirements for the website update included a Blue-Green deployment, hot disaster recovery, high availability and performance, and regional compliance.

SearchStax helped ADI overcome several challenges with the implementation. First, we created APIs so they could programmatically and seamlessly transition between Solr deployments when moving from Static to Production instances for their Blue-Green deployment. The APIs used in the Static deployment included creation and restoration of backups, adding security and creating the vanity URLs. SearchStax also worked with Analog to implement disaster recovery with Cross Data Center Replication (CDCR) to reduce their recovery point objectives (RPO) and provide higher availability across multiple geographic regions.

Results

The Blue-Green implementation allows Analog to rapidly spin up and then delete their Static system when they no longer needed it. Through this process, Analog was able to reduce their cloud deployment costs by more than more than 80%.

The SearchStax APIs allow Analog to programmatically deploy a new Solr instance and seamlessly switch from one cluster to another with minimal human intervention which added to the cost savings. 

SearchStax also helped Analog reduce the RPO time on their system from 24 hours to less than 10 minutes by implementing disaster recovery with CDCR.
