Updation To Exchange 2010 And Migration To AWS Cloud, A Complex Yet Seamless Process

Overview

Communication is the key. It is the fundamental of carrying out any minute task in this world. Bigger the company means bigger the communication network. In today’s technologically advanced world, most of this communication is carried out through emails or messages. It tends to get quite critical for the company’s business to have a great messaging service and the same issue was being faced by one of our clients. The company used Microsoft Exchange 2007 to manage its messaging environment of hundreds of mailboxes in a complex environment. So, we helped this company in upgrading to Microsoft Exchange 2010 and migrating the messaging environment to the cloud to achieve higher availability, cost reduction and flexibility in the process with the help of Amazon Web Services.

Challenges

Service being used previously was quite complex and had several potential points of failure. Apart from this, the Exchange 2007 was deployed in a data center which resulted in different costs like hardware, support, and colocation.

Journey

Mirroar’s expertise with both AWS and Microsoft Exchange helped them upgrade to Exchange 2010 while migrating to the AWS Cloud. To carry out this complex deployment, we began with transitioning from Exchange Server 2007 and related Internet Security and Acceleration (ISA) Server 2006 services to Exchange Server 2010 and Threat Management Gateway 2010 and deployed the Exchange 2010 environment to Amazon Virtual Private Cloud (Amazon VPC). The cloud environment connected to the primary datacenter using BGP via VPN. All the traffic was then routed to through the primary datacenter and then Amazon VPC by VPN. We created AMIs running Microsoft Windows for use on Amazon EC2. The system used separate volumes for the operating system, applications, and storage. Nimsoft was operated on AWS to track the server along with application availability and used Amazon Cloud Watch for basic monitoring.

We used the monthly billing model which proved to be perfect for the client because they only had to pay for the required services and used Amazon EC2 reserved instances which reduced the cost further.

Result

With the help of AWS, the client was able to resize mailbox servers based on storage demand. Even in case of a failure, the multiple Availability Zones improved access to mail services. While the AWS migration was a smooth process, the implementation and production costs too remained in their budget plus the cloud made it easier for them to proactively react to any changes in their business community.
