Why choose between a public or a private cloud when you can have the best of both worlds? Hybrid clouds leverage the strengths of private clouds and public cloud services, resulting in a cloud strategy that lowers TCO; enables greater scalability and higher performance; boosts innovation and time-to-market; and improves operational efficiency and business continuity. Here are a few examples of how organisations are benefiting from hybrid cloud deployments.

  • Greater Data Control
  • Faster Provisioning
  • Higher Efficiency

Hybrid Cloud: Popular Use Cases

In the age of the customer, slow is the new broke: poorly designed application or downtime means lost productivity, reduced revenue and subpar end-user satisfaction. Data center professionals spend an inordinate amount of time and resources desperately trying to keep the lights on instead of devoting more time on developing new capabilities that can help their organizations grow and prosper.

Here are some examples of how IT professionals are bringing the agility and fast-paced innovation of cloud computing to on-premises environments.

  • Enabling DevOps
  • Big Data Processing
  • Temporary Resource Expansion
  • Meeting Regulatory Requirements

The Pros and Cons of Different Clouds

Public Cloud
  • Security concerns: Multi-tenancy and transfers over the Internet.
  • Limited control over data center functions.
  • False sense of cost savings for steady-state workloads.
  • Reverse migration of data from public to private clouds.
  • Economically efficient, especially for short-term workloads.
  • Ability to scale easily especially for test/development use cases.
  • Moving on-premise applications to the cloud is a major enabler.
Private Cloud
  • High capex required to purchase new hardware and software.
  • New operational processes are required; not all old processes are suitable for private clouds.
  • Time and costs associated with infrastructure management and upgrades.
  • Fewer security concerns compared to public clouds.
  • IT organisation retains control over the data center.
  • Higher performance compared to public clouds thanks to on-premise infrastructure.
Hybrid Cloud
  • IT organisation requires new skills.
  • Change management, if underlying workflows are changed.
  • Lack of reliable connectivity.
  • High operational flexibility: Run mission critical workloads on private clouds; dev/test on public clouds.
  • Scalability: Run peak and bursty workloads on the public cloud.
  • Seamless operations across platforms and public cloud service providers.
