Arista Group | Migrates to AWS To Lower Their IT Costs

About Arista

ARISTA is a national company that started its business in the automotive industry in 2003 as an authorized vehicle dealer by providing complete services from sales to vehicle service. With the development of its business, ARISTA has transformed into one of the main automotive companies in Indonesia that provides land transportation solutions for various vehicle brands.

Currently, ARISTA does not only serve the sale and sale of new vehicles but also engages in the rental and auction business of vehicles.

A Brief Summary of AWS Case

The migration carried out by the Arista team began with technical difficulties, namely damage to one of their hard disks. Due to the long ordering time for replacement, the team decided to move to the Cloud. Initially, Arista did not use AWS as their cloud provider but chose another provider to support their running workloads.

However, several issues soon emerged, particularly related to the cloud provider’s services. For example, there was no detailed data or notification regarding billing, which suddenly spiked.

When Arista tried to contact the local partner of the cloud provider, they did not receive any response. Additionally, there was an unexpected version update that occurred without prior information, which further disrupted operations.

Faced with these challenges, Arista Group decided to switch to AWS. They officially started using AWS in March 2020. Since then, Arista Group has been running 100% fully on AWS. Their workloads primarily focus on ERP applications for internal operations called ADMS.

In addition, AWS is also used to support front-office sales reporting, unit order management, and customer sales processes. Overall, most of Arista’s workloads on AWS are dedicated to managing and optimizing the company’s business operations.

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.

• Add 1 server on Public Subnet for Bastion Host.
  

• Using 1 VPC on AWS, Single AZ use Public Subnet and Private Subnet.
  

• Connection for Migration purpose: Connectivity between AWS and Azure will be using existing public internet.
  

• Tools to migrate VM from previous Cloud to AWS will be using CloudEndure. An agent needs to be installed on each On Premise servers. CloudEndure will be initial replicate to AWS, after initial replicate, we will cut over and launch to AWS.
  

• License Windows Server 2008 Datacenter on each server will be provide by AWS.
