Most business today, if they have not yet undertaken a cloud migration, are certainly in the process of planing such a move. The desire to do so is fueled by the multitude of benefits that are loudly proclaimed, including scalability, flexibility and cost-efficiency.
Benjamin Coetzer, Director at local VMware, a Cloud Verified provider Routed, says that before undertaking such a move, companies should understand the many hurdles they face, and how to overcome these.
While there are undoubtedly many benefits, there are also numerous hurdles to cloud adoption, and it is these challenges that CIOs need to be aware of when planning migration.
Some of the biggest challenges revolve around managing cloud spend, understanding the cost components of cloud infrastructure, and of course, how those costs can scale. Additionally, migrating traditional on-premises workloads to hyperscale providers isn’t always a simple equation. Unlike buying physical servers and equipment, hyperscalers charge for communication and disk access in ways that are unfamiliar to most organisations.
The single biggest global challenge currently, and one that is a major issue in South Africa, is the lack of adequate cloud skills. A shortage like this means that a lot of people do not have the relevant cloud skills. A shortage like this means that a lot of people do not have the relevant experience in cloud migration, and thus face a steep learning curve when transitioning from on-premises to the cloud.
Part of the problem lies in the fact that with on-premises setups, IT teams have more control over data access and security. In the cloud, security becomes a shared responsibility, requiring awareness and training across the enterprise. Moreover, as businesses shift to software-as-a-service (SaaS) models, employees also need retraining, in order to adapt to new ways of using applications and accessing data, while still maintaining effective security.
Legacy versus cloud native
Another concern is that technical leaders sometimes try to take legacy on-premise applications and shift these straight into a cloud native environment. Not only do such applications not always work properly in the new environment, but organisations that are used to the usual Capex-type investments for hardware refreshes or perpetual software licenses, quickly find that the cost operation model in a cloud environment is completely different.
It is often the non-IT departments in the business that don’t know how to handle this new cost paradigm model – people like the finance director, accountants and product teams.
There are also significant technical challenges to consider, with connectivity being first and foremost among these. Since connectivity is the lifeblood of the cloud, it is imperative that your business or office park has some form of redundancy built in. The best approach is to utilise two different connectivity mediums, such as a main fibre link, with a wireless connection as a secondary option.
A second challenge here is the issue of locality. This is of concern, due to the nature of compliance requirements – like the General Data Protection Rule (GDPR) and the Protection of Personal Information Act (PoPIA) – indicating that certain data must reside within local borders. It is vital to be aware of the personal information that you are saving in your databases, systems, and applications, as this is stringently controlled and there are strict rules around where such data resides, from a compliance perspective.
Security and data privacy concerns should be among your top of mind thoughts, as such issues play a significant role in hindering cloud adoption. For example, we are aware that the cloud introduces new operating paradigms and governance challenges, such as Shadow IT.
This is where different departments use various cloud services without oversight, something that can easily lead to data breaches of local regulations like PoPIA, and international ones like the US Cloud Act. Such laws add complexities to data sovereignty and privacy, meaning that organisations need to consider these aspects when selecting a cloud provider.
High costs and vendor lock-in
It is also worth noting that one really needs to recognise and address these challenges beforehand. This is critical, because once you’re committed to a cloud provider, its difficult to switch or repatriate data without incurring high costs. Vendor lock-in is a real concern, and carefully planning ahead can prevent your business getting trapped in a situation where options are limited and costs are unforeseen.
This happens because the fees from hyperscalers are often consumption-based when it comes to repatriating data or information out of cloud environments. What occurs is that the providers entice new customers with an offer of huge discounts on their workloads, but this is done because they know that within the contract period, the client’s consumption of their platform is going to grow drastically.
Moving to a hyperscaler cloud is like checking into Hotel California
You can check in but you can never leave – once you have committed, you may find yourself stuck with them – because in order to move out again, it may well cost you more than you would have saved with the original discount.
One more thing to consider is the concept of multi-cloud, similar to the previously coined term ‘hybrid cloud’, where organisations place different workloads with different hyperscalers. This is often considered the next step in cloud migration, but represents further challenges, as it is now about governance, compliance, control, and operational insights across multiple different cloud providers, making the whole process even more complex.
Looking at the big picture, cloud adoption is obviously a move that can be expensive, due to the operational complexities outlined above. However, these expenses can be balanced by the expertise that cloud providers bring in managing risk and operations, as compared to relying solely on internal IT staff, particularly if they do not even have proper cloud skills.
Besides doing your homework before making the move, the best advice for those still seeking to migrate to the cloud is this: Find a trusted partner that has a proven track record in cloud migration. Avoid those that like to throw buzzwords around and instead seek out a partner that will look at your current IT state and your current business processes with a critical eye, and that will be capable of both evaluating your situation and providing ongoing guidance as you move through your transformation journey.
