Compare between IT in-house and Cloud computing

  1. Risk Management

Risk management in Cloud computing calls for changes to be made in the organization and workload profile, as moving data to the cloud platform comes with substantial risks. The risks that can be experienced in cloud computing include data security and cloud failure. Risk management in cloud computing requires one to revisit risk assumptions. An enterprise or organization that wants to move its services to the cloud platform should first understand the changing risks and account for their emergence and then the organization should include risk management in cloud computing. There are more risks in cloud computing compared to in-house when viewing data security. Most organizations have involved a high breed system that makes use of the infrastructure with the public cloud while controlling other sensitive data in-house.

Data governance and security have been a roadblock and a risk to the computing platform. There are some mitigation strategies that can be used against these risks and they include using a private cloud instead of a public one. In addition, the cloud provider should be a trusted one. Though a cloud computing platform is perceived to be cheaper, most IT personnel have chosen to stick to in-house IT because of the concerns of performance, reliability, and security in the cloud platform.

  1. Backup Management

In-house infrastructure does not have an efficient backup system as the cloud platform does. With the in-house infrastructure, there is a need for hardware backup and schedules. There is an increased cost for in-house computing in terms of costs for disks, off-site storage, and tapes.  Using cloud computing to back up this data eliminates such costs. This is more applicable for large files where the vendor needs only to upload files that are required and not the whole database by use of deltas. In cloud computing, there is enhanced disaster recovery and planning in business continuity. With in-house computing, there is also data redundancy, which is eliminated within the cloud platform. An advantage of the in-house backup over the cloud is the speed and most companies have chosen to make a hybrid of the two backups combining their strengths.

With the cloud platform, there are issues with the amount of bandwidth used when transferring files for backup. This can be avoided by the provision of incremental backups by the cloud service provider after the first full backup. Though the data that should be archived should be non-critical ones to enhance real-time objectives as there is a limit on how much data is moved over a network. In-house IT becomes efficient in backing up data that frequently changes in tapes and disks.

 

  1. Security Management

Security is one of the top concerns when it comes to moving to the cloud platform by most enterprises, though it is more secure compared to what most of the organizations use presently. The Cloud computing level of security depends on the organization and the provider of the cloud platform. An in-house IT infrastructure can prove to have better security when it comes to applications that are mission-critical due to the issues of geographical location and resource control of data. These applications are suitable for internal clouds or server virtualization. The external cloud providers, mostly private ones, should demonstrate some level of security required for such programs to run on the platform.

There have been cases of security breaches in cloud computing platforms. It makes it easier for hackers to get information that is online, such as those stored in a cloud compared to information in in-house infrastructure. Moving information to the cloud has had a negative impact on many organizations. These organizations move sensitive data to the cloud platform and they lose responsibility for it. In most cases, they do not have the necessary knowledge on the cloud service providers needed before moving any data. Cloud service providers who have used security measures on data like data encryption and data fragmentation over different servers have increased the security of the data they stored. The only way to ensure that data is secure enough in a cloud is for organizations to ensure that the security measures are applied to the data before they are transferred to third parties. Data encryption should be applied before transferring them to the provider of the cloud service in addition to the encryption that the provider will apply to the data.

  1. Privacy

Among the various risks that face the cloud computing platform includes data privacy. Most of the organizations are using internal clouds more than external ones because of this. The back-office application and database can be used in-house as this provides and regulates data privacy. Compared to the cloud computing platform, in-house IT provides better data privacy.

There are concerns of protecting one’s personal information, especially when it comes to having such information online. In cloud computing, there are at least two parties involved in any transaction which are the agency that uses the cloud service and the provider of the cloud service. One of the issues that arise is how effective control of information can be taken once it leaves the owner of that information to the cloud service provider. A provider of the cloud computing service should thus enhance the privacy of the information by using good security measures, such as encrypting the data and fragmentation of the data across different servers.

Once the organization’s information leaves the in-house infrastructure, the organization is no longer responsible for the information. To maintain data privacy, an enterprise can keep sensitive information within a private network.

  1. Recovery Management

Cloud computing is a better platform in recovery management compared to in-house infrastructure as it lowers the cost and bars for organizations to deploy effective recovery plans. Deploying recovery plans can be just like replicating a log file into a database. In the case of in-house infrastructure, data recovery or disaster recovery can be tedious and time consuming, and organizations can take weeks to get back to the normal routine. In the business world, there are two possibilities of this meaning that they can either fail completely or never fully recover. In-house infrastructure with tape-based backup cannot deliver what the cloud platform can because of the comprehensive strategies of data recovery.

Incorporating recovery management as part of a cloud computing platform in an organization can greatly reduce the process required as well as the power usage required within a shared environment. In the long run, this initiative does not require a large amount of infrastructure and there is a benefit of scalability to grow and flexibility. In cloud computing, data recovery proves to be cost-effective and a way of reaching governance goals and compliance.
