Addressing Bandwidth Challenges in the Hybrid Cloud
Any application infrastructure that relies on a single data center is only as safe as that data center’s physical resources and the competence of its staff. Witness the recent S3 outage at Amazon. When you choose to deploy in a single public cloud, you are delegating infrastructure management to your provider. When you’re exclusively running in-house, private cloud infrastructure, you’re entrusting that management to your own organization. Either way mistakes happen and disasters can strike. The point is, there is increased exposure in a single site strategy. The key advantage of a mixed multi-site, hybrid cloud deployment strategy is that it avoids single threaded exposure by mirroring data across multiple sites, preferably ones that are separately administered.
A widely-used solution for mirroring across multiple data centers is DRBD, open source high availability and geo clustering replication software developed by Permabit partner, LINBIT. Solutions like DRBD replicate data at the block level enabling users to replicate any file system, VM or application from one cloud to another. Because this is done at the OS level, it doesn’t lock you into one public cloud vendor or even a single private cloud solution. Regardless of which replication solution you choose, open or commercial, you need to think about challenges you’ll face in a multi-cloud approach. One big challenge is bandwidth consumption because it’s directly related to the amount of data you store and it’s no surprise that network bandwidth challenges are often listed among the top 5 roadblocks to implementing a cloud strategy.
Permabit’s Virtual Data Optimizer (VDO) provides the perfect solution to address the multi-site bandwidth challenges faced in hybrid cloud environments. Its advanced data reduction capabilities have the same impact on bandwidth consumption as they do on storage, a 6:1 data reduction rate translates to a 6X reduction in network bandwidth consumption and associated cost. Because VDO operates at the device level, it can sit above block-level replication products to optimize data with inline data deduplication and HIOPS Compression before data is written out and replicated.
As Tom Cook recently noted, the need for data redundancy in high availability clouds, increases the financial benefits of data reduction, 2, 3, 4 or more times. Reduced bandwidth consumption extends savings even further. VDO’s advanced data reduction delivers reduced bandwidth cost, increased performance, and improved agility to replicated environments. Now you can be safe and it will even cost you less!
