A Brief Summary of AWS Case

Carried out by the Arista team is starting from the technical difficulties encountered by Arista, which the damage to one of the hard disks, due to the long ordering time, they finally planned to move to the Cloud, but at first, Arista did not use AWS as their Cloud Provider service, but other Cloud Providers to support the workload that is being run, however, while running, other obstacles were found but focused more on the Cloud Provider service itself, for example there was no further data or notification for billing that suddenly spiked, they tried to contact the local partner cloud provider, but didn’t get an answer and the last one was a version update without further info.

Due to the issues experienced, Arista Group finally found another solution to switch to AWS. Arista Group runs with AWS starting in March 2020 Currently, Arista Group is 100% fully running on AWS, Arista’s workload focuses on ERP applications for the company’s internals called ADMS, then other AWS uses are enabled for Front Office Sales Reporting to unit orders that end in to sales to customers, most of the workload is used to manage Arista’s business.

 

The Migration Method

The migration method used by Arista is the Lift-and-Shift method, Lift-and-shift is the process of migrating a workload from on premise to AWS with little or no modification. A lift-and-shift is a common route for enterprises to move to the cloud, and can be a transitionary state to a more cloud native approach. CloudEndure is used to maintain normal business operations throughout the replication process. It continuously replicates source servers, which means little to no performance impact. Continuous replication also makes it easy to conduct non-disruptive tests and shortens cutover windows.

Currently, Arista Group uses AWS EC2 (Database on top of EC2) and their internal ERP system are built on SQL 2009.
