Why the 'serverless cloud' isn't actually serverless

In serverless computing, cloud-based technology is used to process functions and data from a website, app or device. The term “serverless” is somewhat misleading as it suggests that there is no server involved in these computing processes. Instead, physical servers do exist, but are located off-site.

Cloud servers are virtual. This means that they deliver computing capacity via the internet. Users access these cloud computing platforms remotely, making them a highly accessible and flexible solution for companies.

Data centres for serverless clouds

Cloud providers use servers located on server farms or in data centres. These form the backbone of their cloud platforms. Individuals and companies that subscribe to a cloud service provider connect to a huge network of data centres located all around the world.

Automated systems, third-party audits and regular security and compliance checks ensure that these data centres are highly secure and high performing. Even heavily regulated organisations use these public data centres because of the security and computing power that they offer to millions of active users.

What are the features of a serverless cloud?

If the serverless cloud does, in fact, have a server attached to it, what are the attributes of a serverless cloud? Most agree that these systems have some key features:

1. Scalability - It's possible to scale up and down continuously without the need to reprogram or reformat. Burstable capacity opens up new possibilities for business. It gives companies the peace of mind that their servers can handle spikes in traffic without crashing. Clients can easily upgrade the size of their cloud services, normally with a few clicks. Equally so, it's easy to downgrade and reduce spending when the resources are no longer needed.
2. Flexible pricing - Cloud service providers generally operate on a pay-per-use model. As requirements change, companies pay more or less depending on what they need. Pay-per-use and flexible month-to-month contracts appeal to agile organisations.
3. Self-maintaining systems - Since the server and computing power is provided for by the cloud service provider, users do not need to maintain or upgrade their own systems. On-premises servers can be costly and cannot be scaled up or down very quickly. Should something go wrong, the cost to fix an on-premises server is also high. Companies need in-house expertise or must pay call out fees for a technician to attend to any issues. With serverless clouds, the cloud provider manages all maintenance and upgrades on your behalf.
4. Improved performance with serverless clouds -The final key feature of serverless technology is its reliability. Reputable cloud service providers backup their services through clearly defined service level agreements (SLAs). Guaranteeing minimum levels of uptime and availability appeals to businesses that want to ensure their networks are always up and running. Since all security and faults are dealt with by the cloud service provider, businesses can enjoy a robust system with high levels of cyber security.
