3 WAYS HYBRID CLOUD CAN HELP YOUR INFRASTRUCTURE ENSURE CONSISTENT PERFORMANCE
"According to Gartner, 50% of enterprises
will be using hybrid cloud by 2017"
Hybrid cloud environments mix together elements of on-premise systems, private cloud and public cloud services in order to create a solution that isn’t restricted by the capacity of each individual platform. It’s great to resolve a specific problem efficiently and at a cost that doesn’t break the bank, but is it always the optimum solution?
Read on to understand how a hybrid cloud deployment can keep your network running in the event of disaster, and how it can support continued business growth by pre-emptively preventing downtime caused by over-committed capacity.
1. CLOUD DISASTER RECOVERY
One way you can ensure safe fail over when your internal systems go down is by implementing a cloud-based disaster recover (DR) solution on a hybrid cloud architecture. The beauty of the hybrid approach is that if one of your systems goes down – whether it’s on-premise or hosted in a 3rd party data centre – your applications can fail over to the second provider, and your employees can continue to work with minimal disruption.
When to use: Whenever you can! You might not need to back up your entire infrastructure to a hybrid system, but ensuring your business critical apps are accessible in the public cloud means the impact of downtime is reduced. Hybrid cloud platforms can make DR much cheaper, and can ensure recovery is swift and efficient.
When to avoid: Hybrid cloud DR can cause additional complexity in large enterprises. Backing up and recovering huge amounts of data from an on-premise platform to the cloud can be extremely time consuming and impactful, so make sure your bandwidth can support the recovery when required and ensure you have a comprehensive network profile to hand. Alternatives include only backing up business critical applications or data, as long as it’s not of a sensitive nature.
2. CLOUD BURSTING
The term “cloud bursting” is a relatively new one, and is an interesting application deployment model that allows an application that runs on a private cloud to “burst” into a public cloud model. This approach means that you don’t have to try and guess when capacity will spike, and prevents outage or downtime by utilising the extra resources that the public cloud provides. The best part of this approach is that you only need to pay for the additional resources used when you hit that capacity spike that you weren’t expecting.
When to use: When you’re running high performance applications that fluctuate with demand and are difficult to predict.
When to avoid: When you’re using applications that rely on sensitive information, hosting data on public cloud can be risky so explore options such as private cloud, if you think that this could be a problem. Alternatively, if you’re hitting your capacity on a regular instance, it might be worth investing in a more permanent solution.
3. HYBRID CLOUD STORAGE REPLICATION
Cloud storage has a number of benefits – namely that it’s flexible, scalable and relatively cost effective when compared to on-site hardware. However, cloud storage access can be throttled by bandwidth restrictions, often comes with security concerns, and its use is accompanied with data compliance regulations that need to be followed accordingly. An alternative approach is to utilise a hybrid cloud storage model. Supplementing or replicating your internal storage with private or public cloud storage allows you to back up less sensitive data externally from your on site solutions. This solution can then be scaled up or down depending on your requirements, costs, and the sensitivity of your data.
When to use: When you need to keep sensitive or private data secure on site, but also have lots of data or applications that don’t have high risk vectors, and aren’t accessed very often.
When to avoid: When all of your data is high value or of a sensitive nature, continually moving it between a private and public platform can potentially leave it vulnerable to attack by third parties. Negate these security risks by using a private cloud solution rather than a hybrid one.
There are many ways that hybrid cloud can be implemented successfully to prevent an outage caused by a specific problem. Just like private cloud and public cloud implementations, there’s always an optimum solution. For large enterprises with complex architectures, sometimes hybrid cloud is the only way for such businesses to enjoy the benefits of the cloud, but ultimately it always depends on an individual business’s requirements – unfortunately there’s no “one size fits all” model.
