What is Cloud Computing?

Cloud computing is the distribution of different computing services or resources (storage, networking, analytics, software, intelligence, servers, disaster recovery technology, security, etc.) through the Internet.

Cloud computing changed the model of hiring these services. Clients don’t have to buy, own and maintain data centers and servers. Instead, they can have access to the specific services they require on-demand. As a result, clients’ operation costs can be lowered, and they can access an efficient and modern infrastructure.

Benefits of cloud computing.

  • Efficient your budget. Cloud computing supplies the necessary infrastructure without you purchasing hardware, *software (*in some cases), servers, data centers, maintenance, etc.  
  • Easy access to top-notch technology. There is a wide variety of technologies available for you to access and boost your business. In addition, the price will probably be lower than if you buy them because their cost is shared by different clients. 
  • Fast deployment. No matter the geographical location of your business’s branches, the software can be deployed worldwide in just minutes. Your application or service can get the necessary infrastructure to be available globally. To be close to your potential clients around the world is possible. 
  • Scalability. To calculate the resources you will need in the future, provisioning resources in case of peak activity levels is not that crucial on the cloud. You can simply get and pay what you need today (bandwidth, storage, computing power, etc.), during peak activity moments, and so on. You can go up or down in demand for services.
  • Security. Trustable cloud providers have policies, guarantees, advanced technology, and controls to strengthen your security, protect your data, applications, etc., from threats. A team of hundreds of IT specialists of the cloud provider can defend a lot better your server than your company’s IT team of a few people.   
  • Trustability. Cloud providers have a robust infrastructure and redundancy enough to offer you an efficient backup, disaster recovery, guarantees for their services, etc. 
  • More productivity. Cloud computing solves many of the daily tasks IT teams manage (maintenance of software, hardware, patching, updating, etc.). Your collaborators can invest this time in key projects and the development of your business.

Types of cloud computing.

Cloud computing services are generally divided into three categories. Infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Let’s check them out!

  • Infrastructure as a service (IaaS). What it supplies you it’s the necessary IT infrastructure to run your business. Virtual or dedicated hardware (virtual machines or servers), operating systems, storage, networks, etc. it offers a high level of flexibility and control over the IT resources. You pay for every resource as long as you use it.
  • Platform as a service (PaaS). These are the type of cloud computing services that provide you the environment you need for designing, creating, testing, managing, and delivering software applications. Developers don’t have to get servers, storage, databases, network, etc., required for their work. 
  • Software as a Service (SaaS). It offers you a vast menu of software applications delivered through the Internet, on-demand. SaaS providers host, maintain (update, upgrade, patch, fix errors, etc.), and manage the software for you. Clients only have to connect to the application they require through a common browser or application, no matter their location or device (computer, tablet, phone, etc.). 

Conclusion

Cloud computing makes things easier for business owners like you. The money and time it saves you makes it a choice to be considered. Define clearly your business needs to choose the type of service that suits you better.

SaaS vs PaaS vs IaaS – What is the difference?

Today we are going to talk about Cloud Computing. It is the practice of using outside servers that are connected to the Internet for storing data, managing the data, information processing, and other tasks. The most popular types of Cloud Computing are SaaS, PaaS, and IaaS. Let’s see the differences. 

Local server

When you have your own server hosted on-site, you will be responsible for all of the following categories: 

  • Networking. Here you will need the Internet, routers, and all the connection between the devices. 
  • Storage. Storage for hosting data. 
  • Servers. The computers that will offer services. 
  • Virtualization. A way to offer virtual machines. 
  • OS. An operating system like Windows, Linux, etc. 
  • Middleware. Drivers for devices, APIs, application services, etc. 
  • Runtime. – frameworks and environments for developers and services needed for other applications. 
  • Data. – data storing and processing. 
  • Application. Software that will be used for the needs of the company. 

We need this information for the basis of our comparison of SaaS vs PaaS vs IaaS and to understand better the differences. 

SaaS

SaaS is a software as a service. When we talk about SaaS, the client gets directly a software to use. He or she can’t modify the software and gets features based on the plan that he or she has chosen.

The SaaS provider is responsible for all of the previously mentioned categories – networking, storage, servers, virtualization, OS, middleware, runtime, data, and application. The provider must take care of bug fixing, errors, software updates, and adding new features.

Advantages: easy to start, easy to use, no maintenance needed.

Disadvantages: zero control over the software and its development, vendor lock-in that makes it harder to migrate to another,

Typical examples of SaaS are Dropbox, Microsoft 360, Skype, etc.

PaaS

PaaS is a platform as a service. PaaS is a good choice for development. It offers everything already up and running, including networking, storage, servers, virtualization, OS, middleware, and runtime. 

The developers can jump to the action and start writing code right away. The client will need to take care of the data and the applications that will be needed.

Advantages: almost everything is pre-installed, so you can choose what applications do you need and start using them. You don’t take care of the infrastructure or OS.

Disadvantages: the storage is still the provider’s responsibility, so it can’t be 100% secured, which might be more expensive than an IaaS solution.

Typical examples of PaaS are Microsoft Azure, Amazon AWS, Google Cloud, etc.

IaaS

IaaS is infrastructure as a service. In the case of IaaS, you will get an open canvas. The IaaS provider will take care of the infrastructural part – networking, storage, servers, and virtualization. 

The client takes care of OS, middleware, runtime, data, and applications.

It is a great next step when you want to stop worrying about the on-premise server and go to the cloud.

Advantages: you forget to worry about infrastructural problems of your server, pay-as-you-go model, cheaper to start than a local server.

Disadvantages: You still have many things to take care of, a lot more than in the case of PaaS or SaaS. You will need to maintain the system and the software.

Typical examples of IaaS are Rackspace, Amazon AWS, Microsoft Azure, Google Cloud, and many smaller providers.

Conclusion

SaaS is the easiest to manage from the client’s perspective. PaaS is a great option for creating development servers, use and create applications. IaaS is the most basic cloud approach, but it has the highest freedom for the client.
