Cloud Migration Considerations or Guidlines
Cloud migration is amongst the most extensively conversed topics in IT today. It is a scary procedure of determining whether or when to migrate to the cloud. Therefore to make this procedure a little more relaxed for you, here are five things that one should consider before arriving at a conclusion.
- Choices: Private, public or hybrid?
The most primary thing to decide on before approaching cloud migration servicesis if you want to go private, public or hybrid.
A dedicated infrastructure for your business which is managed either by your teams or third-party providers is an advantage of a private cloud. The organization has its own dedicated hardware, functioning on your private network; located on or off premises.
On the other hand, a public cloud migration service offers its facilities over a network which is not a private one and is accessible for others to use. Usually, it’soff-site and offers a pay-per-usage billing outline which is a cheaper solution, once it skill shares resources over various customers.
Hybrid cloud conglomerates private with a public cloud. Generally it is used to upsurgethe infrastructure systems to meet the demands for seasonal businesses, spikes or financial closings. It can be used to handle an application also. Mostly it is used for the storage of data like setting up an application for a public environment (for example a software as a service) while storing complex information in a private one.
- Existing infrastructure utilization.
It is one of the things one would want to access while considering a move to cloud. In IT, businesses generally buy their hardware depending on spikes in order to avoid problems later. By doing that, establishments end up with underutilized equipment, and results in a huge waste of money.
- Compatible operational system.
A cloud or considering migrating to a cloud is all about standards. One needs to keep versions of operating systems and middleware up-to-date when one wants to migrate to a cloud provider.
Cloud service providers (CSPs) should be considered as it does not support end-of-life operating systems or the ones phased out. The same applies to your middleware and databases.
- Availability of Infrastructure.
While choosing a CSP, one should check if the infrastructure is prepared for the workload. Mostly clouds use open standards for reserve and recovery and other services. The tools used may not support online backup of databasesor middleware software, or advanced monitoring functions.
Also, cloud data center location is imperative to take into consideration. If you have some data location restrictions, or iyour users reside in a precise country or geographical region, there are CSPs like IBM SoftLayer that can offer a presence where others might not. Make sure the availability of the service level agreements (SLAs) meets your business requirements.
- Backup policies and disaster retrieval.
How are your backup policies functioning today? Do they fit yourcloud migration provider? These should be an important point that establishments should carefully consider. Cloud providers might have backup policies with a level of customization.
Disaster recovery and business continuity are essential for the smallest companies. Recovery time objective (RTO) and recovery point objective(RPO) are values that define the amount of data one is willing to lose and the amount of time you are prepared to allow for the data to be reinstated.
Hopefully this post will help you make decisions about your cloud migration services.
