Benefits of Virtualization in companies
Virtualization is being increasingly used by IT departments for server consolidation and testing purposes. Virtual servers are used to reduce operational costs and to improve system efficiency. The growth in virtual servers has created challenges for IT departments regarding high availability and data protection. It is not enough to protect physical servers but also take care of virtual server disaster recovery, as they contain business critical data and information. Virtual servers offer the flexibility, but at the same time if a single physical server containing multiple virtual servers fails, then impact of data loss is enormous.
Virtualization Benefits
Companies are adopting virtualization at a rapid speed because of the tremendous benefit it offers and some of them include:
Server Consolidation – Virtualization helps to consolidate multiple servers into one single physical server, thus offering improved operational performance.
Reduced Hardware Costs – As the number of physical servers goes down, the cost of servers and associated costs like IT infrastructure, space etc. will also decrease tremendously.
Improved Application Security – By having a separate application in each virtual machine, any vulnerability is segregated and it does not affect other applications.
Reduced Maintenance – Since virtual servers can easily be relocated and migrated, maintenance of hardware and software can be done with minimal downtime.
Enhanced Scalability – The ease with which virtual servers can be deployed will result in improved scalability of IT implementation.
Sonasoft provides a high-availability solution, protecting data that reside on virtual servers. Sonasoft’s application supports a myriad of email archiving, disaster recovery, backup scenarios. Customers can have multiple physical servers at the primary location and at the offsite disaster recovery location they can have one physical server with multiple virtual servers. Also, multiple virtual servers from the primary site can be easily backed up and replicated to the disaster recovery site.
In the case of Sonasoft, both on physical and virtual servers, the appropriate agents are installed and these agents have a very small footprint. Because of the limited footprint, the impact on these servers is minimal from a performance perspective. With other replication solutions, one has to install the entire application on the virtual servers and this will take a huge toll on performance.
