Avoiding Pitfalls While Migrating to the Cloud

The modern workplace has changed rapidly in recent years as technology has changed, and the Cloud is one of the biggest shifts yet. There are many benefits to cloud computing, such as reduced IT costs, ease of collaboration, and a dynamic and fluid environment. However, as Curt Cornum, Insight Vice President Technology Services, discusses in his CloudCast presentation “Seven Pitaflls that Could Derail Your Cloud Migration Efforts”, there are also things you’ll need to avoid as you make the migration to a cloud-based environment.

The Modern Workplace [1:14]

There are three major things that are “driving” today’s workplace, according to Cornum that can impact the Cloud environment.

  • More and more end users are mobile, so there is a necessity for multiple operating systems (iOS, Windows, etc.) and a need for fluid firewalls and accessibility to important data while employees are mobile.
  • Workloads are crossing boundaries – some on premise and some through infrastructure, creating routing issues.
  • Modern business is driven by data analytics, which means that the traffic flow can become enormous as different people access and input data.

ASSET Model [08:09]

The ASSET Model was created to help businesses understand the different assets in an enterprise architecture that “live within a data center complex”.  The model is broken down into different levels:

  • A – Applications, which are things like messaging, productivity and business planning software, such as ERP.
  • S – Services, which includes overall directory and mobile device management.
  • S – Systems & Security, covering storage, firewalls, web and email security and filters.
  • E – Enabling Technologies, which includes load balancing and WAN optimization.
  • T – Transport, which is how employees access the data (wired or wireless LAN, VPN, Internet.

Workload Migration Pitfalls [10:26]

One of the pitfalls includes moving applications to a public cloud, but users are still using the VPN. Some people are accessing behind a firewall in office and others from an Internet connection from a remote location. This can create a traffic strain as the information travels further than it really needs to and can create twice as much WAN traffic.

Some of the pitfalls of moving infrastructure to a public cloud environment include:

  • Increased WAN traffic
  •  Complex routing filters
  • Chatty Process, Detoured Security Controls
  • Lower Quality of Service (QoS)

For example, a customer calling in over a VoIP call center may experience lack of quality customer service due to the complicated scenario that call must be routed through via a public Internet service.

One solution to optimize cloud service is to route a call that doesn’t need as high QoS over one connection and sending time sensitive traffic over a private network. This can reduce the strain on the system and improve customer service quality for all customers.

A Lifeline to Swing over the Pitfalls [25:18]

Insight Services can help clients avoid the pitfalls of migrating to the cloud. When businesses move infrastructure to the cloud, they lose some control and some visibility, but can get around it by figuring out what type of reporting is offered by their provider. By focusing on networking, productivity, data center collaboration, and understanding how the cloud works, Insight throws clients a lifeline that helps them make the migration successfully without the stumbling blocks other companies face.
