The Covid-19 pandemic has profoundly and in many cases disrupted the lives of billions of people and the business models of companies around the world. Among the effects most relevant to the latter is an apparent acceleration of digital transformation, coinciding with a growing adoption of the cloud to meet the needs arising from the situation arising from the massive use of smart work, the development of e-commerce, the requirements of more complex logistics, etc. As a result, the cloud computing market as a whole has seen double-digit global growth, exceeding 40% in 2021 alone, according to several analysts. compared to the previous year.
A quick scan of the data immediately reveals the role of platform as a service (PaaS), which has taken a global leap. It is therefore interesting to examine the possible reasons for the success of PaaS with companies, based on an analysis of the characteristics of this approach.
What is PaaS?
PaaS solutions provide an out-of-the-box platform on which to install, configure, and operate your applications, with the vendor of your choice managing the hardware, virtualization layer, and operating system.
One of the main advantages of PaaS is its ability to improve a company’s productivity. Developers in particular can derive real benefits from technologies and services, including:
• Database: Here you have the opportunity to quickly implement various mechanisms without any knowledge of administration.
• Artificial intelligence: Pre-trained machine learning and deep learning models provide development teams with significant resources to build applications that incorporate specific AI capabilities without the high cost of purchasing, managing, and maintaining performance , the significant computing power, storage capacity and network capacity required by these applications.
• Kubernetes and other microservices: These have become excellent choices for deploying applications because they offer dynamism and modularity, but are complicated to deploy and maintain, so choose an “…as a service” offer without initial configuration to allow the company to concentrate on its core business.
• Storage: In addition to the well-known file system, object-based storage offers better synergies with application development and is strongly associated with massive and decentralized data storage. By using this solution as a service, you avoid a CAPEX cost model, easily and freely scalable without initial investments and without restrictions.
So why adopt PaaS solutions?
One of the highlights that marked an improvement in IT administration was the incorporation of technology as a service.
Previously, enterprise IT teams had to take care of everything from hardware, operating systems, installing services, and then developing the apps or websites themselves.
Today, we also have to take into account the different challenges that organizations face in the world of IT and cloud, such as: for example, compliance with various regulations, unpredictable costs, data security, data sovereignty.
With this in mind, virtualization and API development enhancements have allowed organizations to bundle these services in an out-of-the-box way. These advances have led to an evolution of cloud usage thanks to PaaS solutions.
The benefits of PaaS
PaaS allows businesses and developers to take advantage of all the important benefits of the cloud. It also allows the sharing of resources between several development teams, avoiding the over-allocation of several assets of the same type in separate silos.
IT system governance and time to market are compromised when managed by different teams, especially in cases where deployment requires budgeting, deployment, etc., permissions, in some cases with the risk of not aligning them with the priorities of other activities. areas. By adopting PaaS models, DevOps and developers benefit from freedom and ease of use thanks to the level of abstraction in management and the possibility of generating automations for the creation of resources. This results in an accelerated time to market, allowing you to streamline the implementation of database services, development environments or storage solutions.
In terms of budget, the paradigm shift from an investment model to a pay-as-you-go “OPEX” model allows for better cost control. In addition, it allows the management of peak loads and test platforms for solutions that would otherwise require an initial investment, with all that that entails.
Finally, PaaS systems can be used to create applications that are offered to other customers and users in Software as a Service (SaaS) mode. SaaS application requirements, including scalability and the ability to manage multiple tenants, can be met by the cloud computing capabilities of a PaaS system.
The conditions for an ideal solution
A suitable PaaS solution must have specific functionalities to offer the best of the IaaS and PaaS world, such as:
Have on-demand capabilities that include instant and automated access and delivery;
Ensure a flexible approach to allow customers to choose a public, private or hybrid cloud solution;
Trust a reliable cloud;
Better integration of IaaS and PaaS components such as compute power, storage and database;
Have interoperability features and an open approach, with the adoption of standards that enable multi-cloud and eliminate the risk of vendor lock-in;
Contain security features that meet the highest standards;
Adapt to new and legacy workloads to minimize business continuity disruptions.
