Cloud – Public, Private and Hybrid

Cloud isn’t a trend, it’s an evolution of how we do business. Depending on the type of data you intend to store in the cloud, you will have to decide if a public, private, or hybrid cloud is right for your business. The benefits of using the cloud are well supported:

  • Reduced IT costs
  • Fast and reliable deployment
  • Increased productivity

Factors to consider when choosing your type of cloud are: how critical the applications you’re putting in the cloud are; what the data protection or regulatory requirements are; how big the application workload are; how integrated applications need to be with the other functions.

The question is no longer “should I implement cloud?” rather, “HOW should I implement cloud?”

Public Cloud

Why might you only want public cloud?

All types of cloud have their tradeoffs.  In a public cloud your services and infrastructure are housed off-site and accessed over the Internet.  Because of this, public cloud is theoretically more vulnerable than private cloud.  But the cloud providers are expected to manage the IT so there are no security breaches or disasters.  The benefit is that public cloud provides the highest efficiency in shared resources.  So, public cloud is most appropriate for:

  • Applications used by many people such as email
  • Collaborative project space
  • Testing and developing applications and codes
  • Incremental capacity for when traffic fluctuates
  • SaaS applications provided by vendors with high-level security

DigiTel Services has strong relationships with top-tier cloud service providers, so we know we are providing you with secure and reliable public cloud.

Private Cloud

Why might you only want private cloud?

Private cloud houses services and infrastructure on a private network.  Because there is a slight chance of security breaches in public cloud, private is the most secure and controlled type of cloud.  Architecture, platform, and services are managed by IT personnel on a private network protected by a firewall.  Private cloud is effective if:

  • Security and control are vital because your software and data are your business
  • Required to abide by data privacy and compliance regulations
  • Company is competent enough to individually manage cloud systems

Hybrid Cloud

Why might you want both private and public cloud?

Hybrid is the most customizable form of cloud because every aspect of your business is located in its most efficient environment possible (internal or external).  To ensure that you’re making the right move by transferring to a hybrid cloud, [Our Company Name] only works with providers who ensure security of access control, authentication, data confidentiality, and encryption.  Scenarios in which you would need a hybrid cloud are if:

  • Company is interested in using SaaS applications and is wary of security breaches
  • Company provides services to different vertical markets

Hybrid cloud is more complex because continuity is difficult to establish between internal private and external public clouds.  The good news is, you don’t have to worry about such complexities because we work with providers who are tactful in linking such separate environments over the cloud.
