Before the arrival of cloud, hosting websites along with other applications was a complex task. Here, complexity refers to the management of resources. The traditional infrastructure like mini data center is also expensive, and so is its maintenance. The architecture needs a strong internet connection 24*7 to ensure the continuous working of websites. Moreover, the implementation of new services like creating a replica of the database and monitoring was also a tedious task. Today, Cloud has emerged as the solution to all these problems. Now hosting a website is just a few click task. Cloud Computing is the technology that gives you access to computing resources remotely in just a few clicks. You will only pay for the resources you will use. And today we will look at key cloud delivery models which will make your life a lot easier!
Every day a new application is deployed in the cloud. Microsoft, Google, and Amazon web services are the leading cloud service providers, and offer services to compute, deploy and test your application. They also provide advanced tools for developing VR and Machine learning algorithms through artificial intelligence. You can even enroll yourself in courses, or take training like AWS training from experts to understand the cloud in detail.
This is a detailed post on cloud computing which talks about the cloud delivery models, what services it offers, and how you can implement it in your applications, no matter what your field is.
Cloud delivery models
On the basis of the services cloud offers, we can count on the following cloud delivery models:
1). Software as a Service (SaaS)
It is the topmost layer of the cloud. The end users experience the applications on demand over the internet. The cloud gives access to many applications for development, deployment, and performing other useful tasks like working on excel, word online, Email, ERP tools, etc.
2). Network as a Service (NaaS)
Cloud offers you to configure, manage and develop networking environment for your application. Here, you can deploy your application in the Virtual private or public cloud. You can set your subnet groups, perform masking, generate static IP, manage domain name system, and add to or remove security groups for all networking layers you need like HTTP, HTTPs, FTP, sFTP, etc.
3). Platform as a Service (PaaS)
Cloud provides a platform for writing, configuring, and deploying your code directly. You don’t have to worry about the machine. Cloud will automatically manage your device, no matter which language, for example, node.js, PHP or Python your code is written. You have to select the right one, for example, AWS provides lightsail service that you can deploy to host your website in any language.
4). Infrastructure as a Service (IaaS)
The most advanced feature cloud offers IaaS which facilitates to use machine resources in the cloud. You can configure your machine according to your need from the vast marketplace. You can select machine image type from Ubuntu, Amazon, Microsoft etc., and can add CPU in batch or parallel for fulfilling your utilisation, choose solid state device memory(SSD) or HDD based on your data input-output speed and so on. So always go for the right one because this architecture would be the efficiency pillar of your organization.
5). Storage as a Service
Cloud offers storage service to your application. Anyone can buy from a small figure of 5GB to terabytes of storage on the cloud from service providers. It will also provide the type of storage you want to buy like a disk, SSD, IOPS SSD, and HDD.
6). Testing as a Service
A lot of software, infrastructure, and other testing tools are now available in the cloud to use like Blazemeter, LoadStorm, Jenkins Dev, etc.
What does cloud offer?
Cloud offers robust services to use that are managed by providers. It has tools to enhance business productivity like Alexa, mail, which can help you set the priority of tasks and grow your business. It provides tools for development, identity and access management, CRM, security, etc. For databases, the cloud offers incredible services like backup and recovery, snapshot service, and replication service. It also has a mechanism for migration service if you want to migrate your database to another service provider. You can always monitor your resources in the cloud, and even set alarms and observe log files. Cloudwatch is one such tool for monitoring your machine. One can scale products and limit the use of resources while ensuring minimal downtime.
Implementation Area & Conclusion
Cloud is expanding in most of the fields now. Companies like Netflix, Siemens, Expedia, etc., have successfully moved their business to cloud. A lot of startups have also opted cloud as it aligns well with their varying business models.
The conduction of advanced scientific research has become easier and faster through the private cloud environment. These fields can range from oceanography, space missions, cryptocurrency projects, robotics, etc.
