The question of migrating server workloads to cloud-based IaaS infrastructure is not “Why?” but instead “When and how?” The “When?” can be anytime with the recent availability of the Windows Azure IaaS platform. The “How?” is a choice from a number of software and service-based solutions. Below I will cover some key questions that you need to answer before migrating to Azure and explain Vision Solutions’ Double-Take MOVE solution for migrating into Azure.
How much bandwidth will be required to migrate my server workload to Azure? - Your server workload may be small and manageable or large and unwieldy. Can you make the best use of your available bandwidth to migrate the server workload in a reasonable time? Does the migration solution you plan to use make use of bandwidth optimization to make the migration faster and more efficient?
How much downtime is acceptable during the migration? - Your server workload may be non-critical, super-critical, or somewhere in-between. How many minutes or even hours of downtime are going to be incurred with your migration solution of choice? How can you mitigate loss of productivity and revenue by making sure that not only is your downtime within SLAs but that it also causes the minimum disruption of key applications and services.
Can you migrate your server workloads intact? – Your server workload is an integral part of your business and you can’t afford to have it change when you migrate it to IaaS. Does the solution intelligently migrate the whole server, including applications, data and system state so that you mitigate the risk of losing key server configuration details?
Double-Take MOVE from Vision Solutions, Inc. is a migration solution that mitigates risk and provides near-zero downtime between physical, virtual, and cloud IaaS platforms. Double-Take MOVE can migrate server workloads from physical or virtual platforms to Windows Azure IaaS using patented real-time replication to make migration cutover as efficient as possible. Applications, data, and system state are migrated in real-time while the original server is still live in production. At cutover, the production server is shut down and the migration replica server in Azure is rebooted and brought online as an identical copy of the original server with the exception of unique network settings for the Azure virtual network.
With Double-Take MOVE, not only is data efficiently moved over the network using real-time, byte-level replication, but network traffic is also optimized using compression and bandwidth scheduling. It doesn’t matter whether the source server is a physical server or a VM. Double-Take MOVE can migrate that workload with the same real-time efficiency and minimal downtime to Windows Azure.
You have choices when it comes to migrating server workloads to Windows Azure IaaS. If you want a simple, proven, flexible solution that can deliver minimum downtime, risk-mitigation and efficient data transfer to make your migration project a success, you need Vision Solutions’ Double-Take MOVE.
