Moving to the cloud has become a necessity for most organisations. Although companies understand the benefits of the cloud, a significant proportion of them decide to return their workloads to a private environment. Why? Concerns about security and lack of control are two important explanations. In this blog we describe the most common pitfalls to avoid when shifting to the cloud. We also explain how to solve these issues and still enjoy the full potential of cloud solutions.
The cloud is an essential aspect of every business strategy that focuses on digital transformation, but it also appears to be a very difficult exercise. An IDC report recently indicated that 80% of companies are expected to repatriate workloads that were primarily part of a public cloud environment. The research states that about half of public applications are expected to repatriate to an on-premises environment over the next two years. The most important reasons are security and performance, but also costs and lack of control.
Moving to the cloud can indeed be extremely challenging for organisations. Here are some of the main pitfalls to avoid:
1. Lack of Vision
Cloud transformation may seem like a technical challenge at first sight, but it will have an impact on the entire company. It can change the way a business operates in many different areas. Think of budgets, productivity, daily operations and development. That’s why a shift to the cloud should always start at the top floor of an organisation. The IT department must be fully supported by the board and have access to all the necessary resources.
Unless the management of the company understands both the benefits and risks of moving to the cloud, this process will almost certainly fail. The cloud holds many mysteries, even for well-trained IT employees. It is a good idea to support them with advice from cloud experts and consultants, especially if you want to avoid the other pitfalls we are about to explain.
A powerful cloud strategy also involves thinking about which workloads can be moved to the public cloud and which workloads require a more private environment. The benefits of the cloud are often so attractive that companies forget to think carefully about the risks.
2. Security Risks
This brings us to the most main reason why, according to a 451 Research commissioned by Hewlett Packard Enterprise, two-thirds of the workload is still located on-premises despite the fact that a majority of companies agree that the cloud offers a positive experience. Data breaches are common news and companies invest a lot of money in the protection of their infrastructure.
Storing data and important files on external services always exposes organisations to new risks.
Of course, you can expect a cloud service provider to handle sensitive information with care and create an highly secure environment. But lack of control is a real concern for many enterprises when shifting workloads to the public cloud. Security issues can cost companies a fortune and the reputational damage can even be beyond repair.
Here are some things to consider when you switch to a public cloud strategy:
- Make clear decisions about who is supposed to have access to specific data and resources. Not all employees should be able to see all information stored in the cloud.
- Always take a risk-based approach when moving assets to the cloud. This also involves securing the devices used to access a cloud environment.
- Encryption is key to all your actions.
- Train your team to understand how to mitigate security concerns in the cloud.
3. Underestimating Costs
Cost efficiency is one of the greatest benefits of a public cloud environment, but many enterprises still underestimate the investment that is required. Providers will usually not charge any costs for the implementation of data, but the transfer can take you several weeks depending on the volume of the data. Many organisations also buy more storage space than what they need.
As the footprint of technology in all businesses continues to grow, companies need a model that develops in alignment with their technological life-cycle. In the end, a 100% public cloud strategy will not always be the most cost-efficient solution. Security is one reason to carefully consider which workloads can run in public and private cloud environments, but cost is definitely another important factor to keep in mind.
4. Compliancy and privacy issues
Security and compliancy are closely related. Especially when you are dealing with sensitive and personal data, changing regulations about privacy are a real concern. Think about the strict privacy rules that are imposed by GDPR obligations. Many enterprise lose track of their data in the public cloud and don’t know who has access. This lack of control can be a real nightmare as you don’t want to risk irregularities. Sanctions are very expensive, but once again reputational damage might be the highest price to pay.
The more data, software and tools an organisation uses, the more challenging compliancy becomes. IT must be able to monitor the tools that are used and where the data is located.
The solution: hybrid cloud
These concerns are the main motivations for companies to return their data to a more private, on-premises environment. Of course, the benefits of cloud solutions are extremely important to remain competitive and to successfully transform your business. This is why many organisations are now discovering the potential of a hybrid cloud solution.
Control is an important aspect of this hybrid cloud environment. It allows an organisation to move part of its applications to the public cloud, while another part remains private. This enables the IT department to stay in control of the most critical operations. They can manage all data and establish protocols for how particular data should be handled. A hybrid cloud environment is also a very scalable solution that will significantly lower IT costs. A purely private cloud is often extremely expensive and time consuming.
In short, hybrid cloud solutions combine the security and control of an on-premises environment with the versatility of public cloud computing. To find the best strategy for your organisation, you can seek professional assistance of a dedicated IT partner. Computacenter has the expertise to understand your needs and introduce a hybrid cloud solution that will benefit your company in the short and in the long run.
