- Lack of data redundancy
First and foremost, public cloud vendors commit significant resources so that they guarantee to their consumers that users are able to have approach to infrastructure easily whenever they need. Although the cloud vendors always try their best to help, it is inevitable for the problems to happen.
What is more, well-publicized outages can result in the threat of operating your apps in a single data center. Cloud engineers demand on redundancy throughout data centers so that they are able to alleviate the influence within a single data center. Moreover, redundancy shortage could lead to a risk in security to your hybrid cloud, especially if redundant duplicates of data are not managed properly throughout data centers. It is rather easier to move virtual machine instances from one data center to another than one large data suite to another.
Cloud engineers can gain redundancy due to taking advantage of a lot of data centers from a single vendor, a lot of public cloud vendors or one hybrid cloud only. Also, although you can gain the continuity of your business thanks to a hybrid cloud, this is still not one only reason to implement this model. Instead, you can save much of your expenses as well as alleviate the risks by utilizing multiple data centers from a single cloud vendor.
The second point to take into consideration is that maintaining compliance constantly could be really challenging in a hybrid cloud as you need to make sure that your public cloud vendor as well as your private cloud are in compliance. Moreover, you have to demonstrate that ways of coordination between the two clouds is compliant.
Apart from that, what you need to make sure is that your card data must not be delivered from a compliant database on a private cloud to a more dangerous storage system in a public cloud. The ways by which you use to prevent a leak on a system inside may not directly transfer to a public cloud.
- Badly built SLAs
Although you feel safe that your public cloud vendor can help you meet all the laws in service level agreement, which is also known as SLA, you can not make sure that your private cloud could live up to that same agreement. In this case, you should create the agreements which depended entirely on your expectations of the two clouds, both private and public.
Additionally, you should remember to gather data on your private cloud under realistic workloads as well as seek for any possible issues when you integrate the public and private clouds to prevent any disruption to the process. For instance, if a key business driver for your private cloud is taking the responsibility of saving your sensitive data, the service agreement should present the restrictions that you can have the ability to use public cloud for some certain services.
- Risk control
When it comes to the side of a business, information security is all about controlling the danger. Cloud computing, especially the hybrid cloud, takes advantage of interfaces named application programming, which is shortly written as APIs, demands on intricate network configurations as well as promotes the restrictions of traditional system admin’s knowledge and capabilities.
And these issues can lead to a lot of risks later. Cloud computing can not be considered to be safer or not than internal infrastructures, yet hybrid cloud is an intricate mechanism that engineers do not have enough experience to control it.
