SaaS, PaaS and IaaS – The Cloud Computing Infrastructure


Cloud Computing model let users access the network on demand to a shared set of configurable features in computing (for example, networks, servers, storage, applications and services) that can be quickly arranged and released with little management effort or interaction of a service.

Cloud Computing is a broad term to name various IT-related services. The way covers a wide range of services, resembles the term “web”, which since 1996 is used as a synonym for the Internet.

Is your company ready for this new reality?

In the most recent survey, technology experts revealed new and fascinating insights into how the internet affects human intelligence and how information is shared and processed.

By 2025, most people will have access to online software applications and share information through remote networks, rather than relying mainly on tools and information stored on their devices or personal computers.

The cloud experts says that it will be more dominant than the actual physical desktop in the next decade. The Cloud Server Hosting is coming and settling for change in various aspects of IT services. The 100% online storage capacity, security as a keyword and lower costs is causing companies to stop increasingly aside the offline storage modes to adhere to this type of service.

The capacity of production by several employees at the same time, online meetings and the fact that there is need for a physical structure brings to the world of technology a new era, towards functionality.

Cloud Computing is a service that can be provided in different ways, which is based on three different structures. They are:

Software as a Service (SaaS):

It is the best known type of online storage, used, for example, by email services. Among the main features are data access via web, centralized management, applications following the model “one to many”, and APIs (Application Programming Interfaces) to allow external integrations.

When To Use It?

Its use is recommended when applications require remote or mobile access, such as CRM software for the relationship management (customer) and management of social networks, marketing.

It is also ideal to use it for a short-term or on seasonal basis, as project collaboration software.

When Not To Use it?

SaaS is not advisable when applications require fast or real-time data processing, follow a law that does not allow data hosting outside the company or the security requirements and SLA are critical.

Platform as a service (PaaS):

This is similar to SaaS. The difference is that, the former is a software delivered over the web and it is an environment, a platform, as its name says, to create, host and manage software.

When To Use It?

When there is a need for teamwork, integration and screening services and database integration. The service is useful when implementing or when there is need for a complex environment for the application. It is also important when many developers are working for each other and there is no need for external interaction.

When Not To Use It?

When the proprietary language might hinder in case you need to change to another provider in the future or if you use proprietary languages or approaches that influence the development process. It is also not advisable in cases of customization, where application performance requires specific hardware or software.

Infrastructure as a service (IaaS):

This one has three subcategories:

A) Public Cloud:

When the infrastructure has standardized shared resources over the Internet;

B) Private Cloud:

Infrastructure following the virtualization of cloud computing, but privately;

C) Hybrid Cloud:

Combines the first two using the characteristics of one or another when it is more convenient.

For contracted services and its resources, monitoring is advanced, there is high scalability and the cost varies.

When To Use It?

When demand is volatile, such as for virtual stores. It is also advisable for companies that grow rapidly and there is no capital for infrastructure.

When Not To Use It?

This is something where you must be careful with the law. Sometimes it is not allowed to outsourcing or keep data storage outside the company. It is not advisable when the performance levels are required for applications to limit access to the provider.

The Informant experts who work with interaction design have an important role in understanding the expectations and reactions of users. To promote better communication and get positive feedback in all product areas, several points are analyzed, such as security and the positive response of the shares, aiming to build a product that fits closely to the user. This is one of our strengths to deliver a functional product quality in different segments.

It is important that each service meets exact needs of each company, which may vary by size, number of employees, practice area and other factors such as the company follows legislation. The Cloud services are improving constantly and moving towards a single goal: Convenience and safety with low cost.
