Hybrid Cloud - Public plus Private Cloud

Cloud is the first step for some firms while it is the final destination for others.

Over the past year, we have witnessed an increasing number of enterprise workloads shifting to the cloud and especially more so to the private cloud. RightScale 2016 State of the Cloud Report indicates that 17 percent of enterprises now have more than 1,000 VMs in public cloud, which is a striking 13 percent increase from 2015. Private cloud, on the other hand grew from 22 percent of enterprises in 2015 to 31 percent.

With bigwigs like PricewaterhouseCoopers, SunGard Financial Systems, JDA Software, General Mills and Coca Cola joining the cloud bandwagon, it is no surprise that several others are keen to follow suit.

But fact remains that most new IT firms are born and bred on the cloud and ignoring the cloud can be costly for older firms. For those already in the business not using the cloud can harm business competitiveness in the long run. But for enterprises with on-premise systems, moving to the cloud is not an easy decision. Re-architecting for the cloud can be expensive and disruptive. CIOs have the added burden of having to choose the right deployment model and public cloud vendor.

How would you like the ability to pick and choose where your organizational resources are placed? Sounds great right? That’s exactly what the hybrid cloud offers.

For companies shifting to the cloud, hybrid cloud solutions are emerging as a logical middle ground and their targeted end state. This is because as the cloud space is maturing, CIOs are gaining confidence with the cloud paradigm and exploring multiple deployment options. Hybrid cloud adoption rose from 58 percent in 2015 to 71 and is set to rise further, according to RightScale’s 2016 State of the Cloud Report.

What is the Hybrid Cloud?

A hybrid cloud is a private cloud that lets organizations tap into the public cloud when and where it makes sense. For instance, an organization might choose to use the public cloud service for an email or workflow application, while using the private cloud for sensitive data sources such as those related to finance or IP.

What is driving the shift to Hybrid Cloud Model?

Back in 2012, Honda UK implemented the hybrid cloud for the company’s IT infrastructure to handle the sudden increase in website usage (Dasgupta, 2015). Due to bandwidth limitations, the company suffered through unexpected web server crashes. This made Honda UK realize that they were in desperate need for scalable bandwidth for their IT infrastructure.

And this could be done by using a Hybrid Cloud.

What makes the hybrid model so interesting is that it has evolved by absorbing the best of private and public cloud models. It provides the right balance of both agility and control over the application to cloud users.

There are several benefits of choosing the hybrid cloud: Reduced time to production, the ability to utilize your existing private infrastructure while exploring ways to leverage the public cloud, IT control over deployment of new projects, greater visibility, reduced latency as compared to the public cloud, better cost savings and so on.

In this blog post, however, we will highlight three main benefits of the hybrid cloud that prove how it is an absolute game changer for those who are on the fence about making the move.

Get Started

While migrating to the cloud CIOs try to ensure three things:

  • That their applications and data are safe on the cloud
  • That migration is generating cost savings
  • To negate (or minimize, at least) disruption to business operations during the migration

Now, let’s delve into how the hybrid cloud covers all these aspects:

Secure your applications and data

Security is rightfully a key concern for many enterprises who are debating the move to the cloud. The most common objection or concern that CIOs have with porting applications to public cloud: Data security

But guess what?

Hybrid clouds may just be the answer to your vexed issue of data security.

Public cloud vendors take the issue of data security very seriously. They comply with the latest security standards and hire the best talent to keep their data centers safe. But businesses are worried about exposing their data to hackers. Shared computing resources could mean a hacker trying to hack into another cloud user’s database might also get access to data from other users in the data center. Another instance that limits businesses to private clouds is when the application collects sensitive data which is governed by industry, financial or government regulations.

However, by adopting the hybrid approach, businesses can store their sensitive data and intellectual property on a dedicated server, within the perimeter of their enterprise, while utilizing high performance and scalability of the cloud for less-sensitive applications and data.

When businesses combine both dedicated and cloud resources, they can effectively eliminate many security and compliance concerns.

Save costs

The bottom line for most organizations and a primary driver for cloud adoption is that the cloud helps them save money and increase profits.

When your organization is using on-premise legacy technology, upgrade becomes a hassle. Sometimes, it could mean ripping apart all your current technology, that you have so carefully built over the years, and replacing it with new infrastructure. With the hybrid cloud, enterprises have the opportunity to create a bridge between their old and new systems, which can result in massive CAPEX and OPEX savings.

Let’s imagine another scenario – you are having sudden, yet occasional bursts in system usage, just as in the Honda UK example we described above. Although they are few and far apart, it could mean spending a colossal amount of money to build new infrastructure to manage these peaks. You know what would be way more cost effective?

You guessed it – the cloud! Organizations can leverage the public cloud for extra computational power – and only pay for it when they need it and for exactly how much they use.

Less money spent on infrastructure = More money devoted to growing the business!

Unlike the scenario with on-premise technology, companies can take advantage of seamless, disruption free scaling by designating cloud resources for unexpected projects, rather than drumming up local IT infrastructure. This brings us to our next point.

Expand Capacity Without Disruption

Adding capacity on-premise is not cost-effective by any means – whether it means accommodating additional racks in your data center or building a brand new one altogether. Going the Hybrid route offers an attractive alternative by allowing you to minimize disruption to existing operations as much as possible.

Have you heard of Cloud Bursting?

One of the most attractive features of Hybrid Cloud – is the ability to “burst” to the public cloud when additional capacity is needed.

The concept of cloud bursting is especially relevant for organizations with constantly evolving capacity needs. When there is a sudden spike in demand for computing capabilities, enterprises can turn to the cloud to get immediate additional capacity for their non-critical applications handling non-sensitive information, while continuing to use their internal systems for their regular needs.

So with the hybrid cloud, you have your on-premise infrastructure supporting your normal business workload, plus you also have the advantageous option of leveraging the public cloud, when you are in need for more computational power than what your data center or private cloud can offer. Also, when one component of the hybrid cloud is down, you have the advantage of leveraging the other part.

Not only do enterprises have the option of deploying the application locally and then bursting to the cloud to meet sudden surge demands, but they can also move the application entirely to the cloud, when required, so they can use their local resources for more business-critical applications.

Is hybrid cloud a win-win then?

Despite hybrid cloud being slightly more challenging to manage, the overall benefits far outweigh the costs associated with it. By allowing you to manage important applications and critical data securely and most importantly, reducing overall risk, the hybrid cloud could offer you far better flexibility and cost savings.

If you’re considering the option of a hybrid cloud for your organization, then you should explore options with various cloud infrastructure providers and leverage their knowledge to determine the best strategy to implement the hybrid cloud for your business needs.
