Multicloud as a Service

Cloud computing is revolutionizing the way organizations work by providing access to the infrastructure needed to run sophisticated applications with flexibility and agility. But there’s no single way to go about it.

The available options are frequently a source of confusion. Is a private, public or hybrid cloud the best solution for your organization? What are the strengths and weaknesses of each?

All three cloud deployment options carry similar overarching benefits – reliability, performance, scalability and cost-effectiveness – but some are inherently better suited to certain types of organizations, or organizations of a certain size.

Let’s weigh them up.

Private cloud

Exclusive use in a dedicated private network means more visibility and control

A private cloud, also known as enterprise cloud, can exist on- or off-premises. Either way, computing resources are used exclusively by one organization and maintained on a dedicated private network. This means the business is responsible for management and maintenance, but can easily customize its resources to meet specific IT needs.

Private cloud affords a higher level of visibility and control, without many of the security concerns – real or perceived – that tend to be associated with the public cloud.

Scalability, mobility and high cost of ownership may be challenging

Private cloud is an expensive option because, over time, servers need to be replaced. Scalability can be impeded by the need to make further infrastructure investments if the cloud data center is hosted on-premises. Private cloud can also make mobile accessibility more challenging.

Works best for:

  • Large businesses that need advanced data-center technologies
  • Organizations that require highly robust security with direct control over information technology workloads and underlying infrastructure
  • Highly regulated industries

Public cloud

Shared infrastructure means no maintenance and lower costs

With public cloud, a third-party provider is responsible for management and maintenance and your data is stored in their data center. All infrastructure, hardware and software is owned by that provider and shared with other organizations.

Public cloud offers high elasticity and easy scalability at very low cost, which is why it’s by far the most popular choice.

The reduced complexity and responsibility mean less pressure on your IT resources and, with flexible pricing based on usage, your organization can focus IT investments elsewhere.

Costs may rise; security could be a concern

The cost of ownership with public cloud can rise exponentially with large-scale usage for larger organizations. It also doesn’t offer the required degree of security and immediate availability for mission-critical IT workloads.

Works best for:

  • Organisations with varying resource requirements
  • Software development and test environments

Hybrid cloud

The best of both

As the name implies, hybrid clouds combine private and public clouds to offer the best of both worlds. Data workloads and applications can be moved between the two environments for greater flexibility. You can run IT workloads in the private cloud, augmented by public-cloud resources for additional capacity to cater for spikes in demand.

This option ensures reliability (with services spread across multiple data centers), improved security without compromising on scalability for less sensitive IT workloads, and the flexibility for policy-driven deployments for distributing workloads between private and public infrastructure based on requirements.

Complexity, control and costs may be a challenge

A hybrid-cloud environment requires thorough integration and total compatibility across the organization’s cloud infrastructure. This can be problematic for public cloud environments where there’s no direct control.

A hybrid model invariably introduces added complexity, which can also mean additional costs – although these can be offset by paying for additional public-cloud capacity only when it’s required.

Ultimately, your decision to go with a public, private or hybrid cloud depends on a range of factors. It’s important to weigh up the strengths and drawbacks of each option and get expert guidance along the way before making a decision.
