Hybrid cloud is a classic merging of private cloud and public cloud. It’s like the hybrid cloud proudly brings forth the best of both worlds – public and private. The concept behind the hybrid cloud is that an enterprise can gain the benefit of cost effectiveness and scalability of the public cloud and, at the same time, the data and the applications remain protected from vulnerabilities by using the private cloud. Sounds lucrative, doesn’t it?
Like everything under the sun, hybrid cloud has its own share of advantages and disadvantages. Let’s focus on the benefits first.
Advantages of Hybrid Cloud:
- Performance Improvement: Hybrid cloud implementation ables the user to work on a healthy and secure network for application development and delivery. Thus, applications can serve from one environment to other without technological error.
- Expanded Capacity: The amalgamation of private and public cloud overcomes a number of development restrictions that existed in the distinct ones. So, the laborious tasks associated with the cloud operations are reduced greatly here.
- Better Scalability: Hybrid cloud computing ensures easier scalability. The cloud size constraints, especially with private cloud, does not remain a major challenge with hybrid as the option to scale up or down is always available.
- Tougher Security: For the companies skeptical about hosting data remotely citing the security reasons, the hybrid cloud would be more secure to keep sensitive data outside a public cloud environment. It allows the users to have proper data access controls without exposing mission-critical data or applications to the vulnerabilities. You can always be satisfied that your data is safe behind the protection of your private firewall and private gateways.
- Lower Cost: Hybrid computing enjoys low initial investment and low cost of operation. It brings significant OPEX and CAPEX savings to the businesses by bridging the gap between old and new systems. It can easily beat the pricings for the private cloud and offers a tough challenge to public one as well.
Now, let’s have a look at the other side of the coin. Like everything else, a hybrid cloud doesn’t come without its pitfalls and anomalies. Here’s a sneak peek at the possible negatives of the hybrid cloud:
Disadvantages of Hybrid Cloud:
- Infrastructural Dependency: Dependency over internal IT infrastructure is one of the major drawbacks of hybrid cloud implementation. To alleviate the impact of outage one would need to ensure redundancy across the data centers. This can be ensured by using numerous data centers from a single vendor or by engaging multiple cloud service providers.
- Complex SLAs (Service Level Agreement): The major complication with hybrid cloud arises from poorly formed SLAs because of variation in the cloud structure. One needs to have SLAs drawn in depth for both your private and public cloud providers to ensure that they can meet your targets and you also need to have a realistic approach towards allocation of workload. Keep a watch for potential integration issues that can disrupt services.
- Compliance Issue: Compliance between private and public cloud is a difficult parameter to achieve in a hybrid relationship. For proper compliance, you will have to ensure that both providers are compliant to your norms and also the data transferred between the two are protected against malpractices.
- Networking Complexities: In a hybrid setup the network plays the most important role as a network is essential for seamless transfer of data. Most important, the APIs (Application Programming Interface) used in hybrid environment demand complex networking as well.
One needs to evaluate both the advantages and disadvantages of a particular virtualization environment before opting one. Hybrid cloud often remains the only solution for companies that need to comply with data security and ease of cloud operations as the same time. Public cloud induces a choice of control and flexibility while the private one tightens the security.
There’s no denying the immense potential in a hybrid cloud, but it’s not always sunshine and rainbows. Hence, choose wisely!
