As a world-class IT company employing high-end cloud application developers, Andersen closely monitors all the important trends taking place in the cloud. That is to say, we are fully aware of the fact that we are living in a connected, mobile-first, and data-driven world. Hence, to succeed, we should exceed all our customers’ expectations whenever it comes to cloud application services. Today, we have decided to dive more deeply into this important domain.

To begin with, by around 2025, there will be roughly 100 zettabytes of info stored in the cloud. Is that a lot? Well, as a zettabyte equals a trillion gigabytes, it is! Simultaneously, the share of cloud-based apps is also going to reach record heights. For instance, the cloud application market size is projected to reach $168.6 billion. To put this into perspective, back in 2021, it was only $133.6 billion. On top of that, all those enormous volumes of data and investments are associated with high-value corporate databases, not with ordinary users. Among other things, as of 2022, approximately 60% of corporate info, taken together, is stored in the cloud. In 2015, it was only 30%. Thus, the issue of cloud application development should be prioritized.

What is cloud application development all about?

What is a cloud-based app? As Business Insider puts it simply (and rightly), it is a Net-based program, which, at least to some extent, relies on processing and storing some of its data via the Internet. In fact, that is what we call ‘the cloud’, i.e. the Global Net. As Investopedia puts it, ‘the cloud’ might cover ‘storage, servers, databases, networking, and software.’ Thus, cloud-based apps rely on remote databases and cloud computing, not on proprietary hardware or local storage.

Why do people and companies opt for cloud-based solutions, with all the associated risks, e.g. like entrusting your data to an external party?

As TechTarget puts it, the advantages are as follows:

  • Cloud applications are almost instantly available and can quickly respond to your business needs in terms of ordering, deploying, and applying them;
  • Cloud-based apps offer you the ability to benefit from simplified operations as they are normally easy-to-use and master. Simultaneously, you are not the one responsible for maintaining them and troubleshooting;
  • When you realize that you need new features, cloud solutions can be quickly scaled up, as all you need to do is to start paying for a more advanced pricing plan;
  • Abundance of APIs for easier adoption and usage;
  • Optimized costs, as end-users do not need to spend money on developing, testing, deploying, maintaining, and upgrading the software they use;
  • Advanced capabilities in terms of data sharing and transfer;

Owing to these pros, cloud-based service providers have become a fact of life in almost every country. For instance, the following list of top ten cloud vendors, as of 2021, speaks for itself:

  • Microsoft;
  • Salesforce;
  • Oracle;
  • SAP;
  • Adobe;
  • ServiceNow;
  • Workday;
  • Intuit;
  • Zoom;
  • UKG.

Common cloud application models and how they differ

There are several approaches to cloud-based solutions in existence. However, they are easily distinguishable from each other on the basis of classes and purposes.

  • For regular end-users, with no special tech knowledge, the only applicable type is SaaS (Software-as-a-Service). Within this framework, an application is ‘fueled’ by the vendor’s infrastructure. Users are granted subscription-based access to it to resolve various tasks, such as video conferencing (Zoom), project management (Trello), documents (Google Docs), etc.
  • Infrastructure-as-a-service offerings, abbreviated as IaaS, are used by system admins and networks architects as an alternative to costly in-house infrastructures. By ordering them, companies obtain enough storage, advanced server infrastructures, and hardware to process their data. The most well-known example of this class is AWS, a partner of choice for countless companies around the globe.
  • Finally, Platform-as-a-Service solutions, aka PaaS, are intended for software engineers requiring pre-configured environments to build and deploy their own solutions. As such, these ecosystems may include systems to manage databases, web-based servers, backup solutions, etc.
