Private Cloud VS Managed Cloud VS Public Cloud

Cloud-Computing

Introduction:

Evolution is going on in IT right now. And that, of course, encompasses everything from workload automation to server automation, network, database, etc. It’s really a piece of a bigger puzzle — a very important piece — because, without data, most organizations would be nothing more than a bunch of people on computers piled up. All these factors are driving more companies to adopt workload automation and get it going in their environment.

Cloud computing can help a business save man-hours, but only if the IT department takes full advantage of workload automation tools. As data centers evolve toward cloud computing, so must workload automation tools. Cloud computing in particular has spurred growth where workloads are concerned.

It is important that organizations do their homework up front to determine which cloud model will best suit their needs. The following attributes of the different cloud models should be considered: Private cloud, Managed cloud or Public cloud

Definition

  • Private cloud: Infrastructure is owned and operated by a single organization and is typically managed internally
  • Managed cloud: Infrastructure is operated solely for a single organization but owned and managed by a service provider.
  • Public cloud: Service provider makes infrastructure available over the Internet on a pay-per-use basis.

Privacy, Security and compliance

  • Private cloud:
    • Most-direct access, control and governance
    • Can be constructed to comply with industry and government regulations
    • Requires replicated physical infrastructures to comply, which may reduce ROI
  • Managed cloud
    • n Delivers disciplined governance and regulatory compliance
    • n Managed by experts with best practices
    • n Secure private compartments, intrusion protection and virtual and physical machines
  • Public cloud
    • Meets requirements for non-regulated workloads
    • Custom country regulations may rule out the public cloud as an option

 Availability and Performance

  • Private cloud:
    • 100% dedicated compute resources shared across workloads
    • Delivers only to the limits of the infrastructure and its bursting capabilities
    • Internally defined, customizable service-level agreements (SLAs)
    • Organization owns maintenance responsibilities
  • Managed cloud
    • n Fast access to scalable infrastructure
    • n Selectable data center locations to comply with requirements
    • n Standard SLAs, high availability
    • n Shift of maintenance and support responsibilities to the provider
  • Public cloud
    • n Compute power not dedicated/guaranteed
    • n Standard SLAs
    • n Ideal for bursting to maintain operations and accelerate productivity
    • n Maintenance responsibilities can rest with either the service user or the provider

Finances

  • Private cloud: CAPEX required for base environment
  • Managed cloud: OPEX aligned with and managed in terms of changing demands
  • Public cloud:
    • OPEX aligned with changing demands
    • CAPEX shifted to the provider

Flexibility

  • Private cloud
    • Can be provisioned in minutes after initial setup
    • Is very elastic for moving services
    • Can burst to public and private managed cloud
    • Enables developers to define specific environments/ infrastructure that meet their application’s characteristics
    • Makes it easy to customize and replicate environments
  • Managed cloud
    • Shift of CAPEX to the provider
    • Quick setup and rapid provisioning
    • Quick and easy scaling
    • Enterprise management tools and controls
  • Public cloud
    • Ideal for distributed development environments
    • Can be provisioned in minutes
    • No contract—standard, fee- based service
    • Ad hoc access
    • Unlimited scalability
    • Doesn’t offer the ability to customize infrastructure to suit an application’s requirements

According to the US Department of Commerce, two of the biggest challenges that businesses seeking IT outsourcing face is the cost benefit rationalization or justification and inexperience. Our clients took deliberate steps to overcome these challenges, by trusting easySERVICE.
