IT experts flocked to Barcelona last week for four days of VMworld Europe, where they could be found on the stage and in the audience for killer keynotes, breakout sessions on breakthrough technologies and helpful hands-on labs.

Among the ‘aha moments’ for attendees interested in increasing their knowledge about cloud infrastructures was the debunking of the many misconceptions about public cloud deployments that can compromise a successful data center modernization effort.

Wherever you are on the cloud adoption spectrum, you should know what’s a myth and what’s reality when it comes to architecting and rolling out you cloud-based solution.

#1:  MANAGEMENT TOOLS

Myth: It’s easier to learn a cloud provider’s proprietary management tools than it is to find a cloud platform that will run on all the tools you use today.

Reality: Common management across an on-premises data center and the public cloud is one of the top reasons why VMware customers choose VMware vCloud® Air™. You can create a unified platform between on and off-premises with 100% VMware vSphere® compatibility. The truth is, it’s that easy!

#2:  WORKLOADS

Myth: Any workload that runs in an on-premises data center can run in a public cloud.

Reality: Not all workloads are suited to the public cloud. Among the criteria you will want to consider when considering a move to the cloud are:

  • What service levels do they have, and why is this important?
  • What resources do they consume, and why is this important?
  • What network security model is used on premises and how is this expected to be used in the cloud?
  • What data change rate do they have, and why is this important?

Since vCloud Air is built on vSphere, any application that runs on-premises will also run on vCloud Air, whether it is an existing workload or part of new application development. vCloud Air supports over 90 operating systems and 5,000 applications.

#3:  SCALABILITY

Myth: The cloud is infinitely scalable – no planning for the future is required.

Reality: More might be better as your needs and cloud workloads grow, but it is still  important to think through your availability, manageability, performance, recoverability, security and risk management needs today and down the road, and make sure you can implement technologies to satisfy them. These include virtual data centers, virtual machines and applications, network services, storage services and monitoring.

#4:  EQUALITY

Myth: All public clouds are created equal.

Reality – not all types of cloud platforms, or cloud providers, are suited to every organization. Depending on the cloud type or provider you choose, you may face costly and time-consuming challenges such as the need to learn new tools and skills, or having to re-architect your applications in order to run on a proprietary cloud platform.

When evaluating cloud solutions to modernize your IT architecture, consider the following:

  • Infrastructure Extension – Speed with which infrastructure assets can be ready for use in a cloud environment
  • Infrastructure Replication – Compatibility of the cloud environment with existing on-premises infrastructure
  • Security and Isolation – Compliance with application and security requirements
  • Resource Balancing – Ease with which workloads can be moved to the cloud and back
  • Network Ops and Management – Ability to use existing tools, processes, and interfaces for cloud management

#5:  DATA PROTECTION

Myth: Cloud data backup means you don’t have to follow the longstanding 3-2-1 rule.

Reality: Following the 3-2-1 rule is a best practice for cloud-based data backup. Here’s what you need to know: The 3-2-1 rule:

  • 3 copies of your data: production data, backup and its copy
  • 2 different types of media to store copies of your data (ex. disk storage and tape)
  • 1 copy of a back up file offsite (to the cloud)
