These days, every company has cloud adoption square in their sights. And frankly, it’s a matter of survival. But making the switch to the public cloud is difficult, weighted by legacy systems and incompatible architecture. Fortunately, virtualization may hold the key to success.
In the latest edition of our Partner Spotlight series, VMware Service Provider NTT Communications shares insight into the burgeoning area of Virtual Infrastructure as a Service, and how virtualizing infrastructure is challenging the status quo of public cloud migration.
Before we dive into the specifics outlined in the whitepaper and how virtualization is revolutionizing the migration process, let’s examine a few of the benefits companies can realize in the public cloud.
The Race to The Public Cloud: Benefits and Challenges
For many companies, migration to the public cloud is business necessity driven by the digital transformation directives handed down from company leadership. However, adopting the public cloud is a double-edged sword – on the one hand, companies can take advantage of the numerous benefits offered by the public cloud including:
- Highly agile computing resources that can be provisioned and abandoned with speed.
- Users are charged ONLY for the services they use.
- Services are affordable.
Yet, on the other hand, companies must continue to manage the legacy IT infrastructure they have invested in for years. Consequently, most legacy systems lack the modern architecture now standard within the public cloud making migration between the two exponentially more difficult.
The Migration Migraine: Migrating Existing IT Assets
In order to migrate such legacy applications to the public cloud, major application changes are required. Modern web systems have been optimized to guarantee high levels of availability for application architecture by using multiple stateless web servers. To a legacy system using IT infrastructure features like clustering, they may as well be speaking a different language – which they are!
Existing applications must be refactored to be stateless and aware of parallel distributed processing. A difficult task that can require huge amounts of technical resources. Avoiding such changes to applications can save companies time and money.
A Match Made in the Cloud: Virtual Infrastructure and The Public Cloud
Fortunately, as featured in the NTT Communications whitepaper, it is possible to migrate existing IT assets to the cloud without the need to modify the underlying application. The solution: Virtual Infrastructure.
Virtual Infrastructure offers a number of exciting benefits including:
- A decrease in the number of physical servers required.
- Entire servers can be backed up and migrated.
- Application infrastructure services can be provided without application changes.
Kauro Fukumoto, the author of the whitepaper, says it best, “While public cloud is a revolution of how IT is consumed, virtualization was a revolution of how IT is deployed.”
NTT Communications Brings Virtual Infrastructure-as-a-Service to the Public Cloud
Thanks to several new functionalities, NTT Communications’ enhanced Enterprise Cloud Services offers IT infrastructure hardware as a cloud service, making it possible to deploy a familiar virtual infrastructure in a public cloud environment. NTT Communications is providing the services needed to migrate existing applications to the cloud unchanged, while still enjoying the advantages offered by the public cloud.
