Cloud Fundamentals

Currently, the Cloud industry is over one hundred billion dollars, with rapid and consistent growth. In the industry, there are several world players in a specific and productive environment.

Google has been building data centers and communications networks for more than 20 years, being one of the leading operators in storage, infrastructure rental, and managed services.

In the past, these data centers have been customers’ assets, being maintained and managed locally as YouTube, Google Maps, or Android.

After several years analyzing the market and behavior in the management and use of local resources, Google decided to make its assets available to the public to position itself in the new digital transformation, so that large-scale organizations have advanced technology in their own business.

This transformation is based on four pillars:

  • Dynamic self-service: Customers access a self-subscription mode, pay, and start using resources immediately without human intervention.
  • Network access: Clients access services through the Internet.
  • Distributed resources: volume of clients (individuals, organizations) share the same infrastructure in real-time and dynamic.
  • Scalable infrastructure: Cloud clients have the possibility to increase or decrease the resources and infrastructure in semi-automatic mode.
  • Managed service: Cloud clients pay in real-time for the current use of what they consume, and it is not necessary to reserve or pay in advance for hardware or software.

Delivery Models

Public cloud providers offer their services to individuals, companies, and any other public body or entity. In addition, they make significant investments in data centers that involve software and hardware.

In contrast, a private cloud is an environment reserved for the sole purposes of an organization or entity for exclusive use and in subscription mode and costs for its use.

Some examples of companies have chosen to use data and applications in a private cloud for security reasons in order to comply with specific regulations. There are alternatives when configuring the private cloud. The first option is to configure and build it in local customer data centers. The second option is to configure it in a private hosted cloud.

A hybrid cloud is a combination of a public and private cloud with some level of integration between the two. 

A multi-cloud environment is similar to a hybrid one because the customer is using more than one cloud service. It can include only public clouds, only private clouds, or a combination of both.

Common Service Models

Cloud services are typically deployed based on the end-user (business) requirements. The primary services include the following:

  1. Software as a Service (SaaS)

SaaS is a software delivery method that provides access to software and its functions remotely as a Web-based service. Instead of paying an upfront fee to purchase and license software, SaaS customers pay a recurring fee to subscribe to the service. In general, they can access the SaaS from any Internet-connected device, any time day or night. Well-known examples of SaaS include Salesforce.com, Microsoft Office 365, Google G Suite, Dropbox, Adobe Creative Cloud, and others.

  1. Platform as a Service (PaaS)

PaaS is a Software and Hardware platform, which is managed as services. For example, the management of a telephone exchange. Instead of acquiring a Siemens telephone exchange, it can be purchased as a service. Here, the platform is outsourced. Most PaaSs are designed for developers and aim to simplify the process of creating and implementing software. For example, a web developer could use a PaaS that includes operating system software, web server software, a database, and related web development tools. The leading PaaS providers include Amazon Web Services, Microsoft Azure, IBM, and Google Cloud Platform.

  1. Infrastructure as a Service (IaaS)

Computer infrastructure, such as servers, databases, storage, and networks available as a service, is popular with companies that appreciate the convenience of the cloud provider managing its entire IT infrastructure as a turnkey.

This concept allows excellent savings in companies since the result of paying only for the computer resources they use. Major IaaS providers include Amazon Web Services, Microsoft Azure, IBM, and Google Cloud Platform.

Aside from SaaS, PaaS, and IaaS being the three most attractive models, providers often use other definitions aimed at mass marketing. For example, some offer databases as a service (DBaaS), mobile backend as a service (MBaaS), functions as a service (FaaS), or others.
