The Pros and Cons of Cloud Storage

Pros and Cons of Cloud StorageThe hype surrounding cloud storage continues to grow, and yet, the actual pros and cons of the technology can get lost in the excitement of added features and functionality. While most organizations are now employing some type of cloud services, cloud offerings continue to expand into the data center infrastructure. Here is a short list of pros and cons of cloud storage in relation to data backup and disaster recovery.

Cloud Storage Pros

First, let’s look at the three most prominently presented pros of opting for storage and backup in the cloud:

  • Reduced Cost: The most prominent factor is cost. By moving backup data to a cloud environment businesses can replace a traditional capital expense with an operating expense. Operating expenses can be easier to get budgeted and are widely seen as less of a commitment.
  • Ease of Use: The second factor is the ease of use. Most cloud options run on an automated scheduler and reduce operator intervention. This cuts down on the skills and time required to administer the solution.
  • Flexible Infrastructure: The third factor is the relative absence of a need for dedicated infrastructure. This factor eliminates the need to plan for hardware refreshes and allows businesses to only pay for what they use today.

While these pros need to be taken into consideration, it is important to consider the cons before jumping to a conclusion.

Cons of Cloud Storage

Here are the three primary cons associated with cloud storage:

  • Wide Area Network Connectivity: Even with the advancements in deduplication and compression; replicating data up to the cloud requires a healthy WAN connection from the telephone pole to the cloud providers’ POP. The other side of the coin can be more problematic. Daily replication of data may not accurately represent the WAN requirements to restore data from the cloud. Be sure to have a detailed conversation on recovery time objectives for a file, folder, server, and an environment wide disaster.
  • Resource Sharing: By definition public cloud is a shared resource. This brings up certain considerations around how resources are distributed and prioritized. Cloud providers are set up for certain thresholds of activity. How will a cloud’s availability respond to wide-scale outages or surges in user activity? These questions are addressed both in a cloud provider’s SLA and by compliance regulation standards. Be sure to understand the potential for slower speeds and limited availability before committing your data to the cloud.
  • Cloud Security: This is an ever-present concern in all aspects of technology. Many cloud providers will offer different levels of security with different prices. These options can include private VPN into the cloud, dedicated bare-metal hardware and varied data encryption compliance. Each of these carries with them an additional cost, so carefully consider the correct mix of security for your data at each step as the data is moved from on-premise to the cloud storage.

Regardless of the pros and cons, cloud storage is a useful tool for architecting a robust data backup and disaster recovery environment.
