It is estimated that by 2017 nearly half of large enterprises will have hybrid cloud deployments, driven by their need to balance cost savings with performance, security, scalability and agility. Hybrid cloud deployments, in which some applications are hosted in a private cloud and others in the public cloud, offer the best of both worlds: Dedicated servers for applications that require a higher degree of security, compliance and control, and public clouds for less sensitive applications and data.
In reality, however, we should start to see this migration to hybrid clouds move much more quickly than industry predictions. Let's take a look at some of the reasons why:
- Enterprises will look at the next set of applications they want to take to the cloud. If they initially deployed a private cloud for security or compliance issues, enterprises will weigh moving some to the public cloud this year to gain greater efficiency. Likewise, businesses that dipped their feet into the public cloud will start to look at the benefits of cloud hosting services to move their mission-critical applications to a private cloud. Most cloud deployments that started as small pilot projects introducing limited cloud services or small infrastructure investments have begun to snowball into much more substantial IT overhauls that necessitate a mix of private and public clouds.
- Agility rules the roost. Agility has taken over as the number one reason enterprises say they are migrating to the cloud, surpassing "cost savings." Many businesses have already adopted some sort of cloud model and have squeezed all the capital and operational expenditure savings they can out of their current cloud configuration through virtualization and automation. Next on their agenda is making the enterprise more agile, and that means they'll continue to grow their investments in areas such as usage metrics, self-service offerings and automated provisioning.
- Mobile cloud initiatives are growing. Enterprise hybrid clouds can take on additional importance if they link to users' devices. There are two benefits to involving users in a hybrid cloud:
- Improving governance by providing end-user security and device management, particularly as BYOD grows within the enterprise.
- Enhancing performance by positioning performance-critical elements of an application close to the user.
Some applications that are better suited to dedicated hardware may never be migrated to the cloud, but the hybrid cloud approach allows for this type of tailoring of application to platform, to get the best out of each application. Whether it happens this year or by 2017, enterprises have gotten a taste of the hybrid cloud and will move quickly to reap the benefits it offers.
