Many IT managers are reviewing their options for picking the right approach to cloud computing. Here’s a look at four major types of cloud technologies which can be adopted by an organization.
Cloud models are continuing to evolve as business drivers push more organizations towards a more globally distributed infrastructure. Many companies are actively moving parts of their environments into the cloud for more efficiency, agility and capabilities around growth. This is a major push which has helped data centers come to the forefront of the technological evolution and has allowed more organizations to leverage their services. Costs are coming down and the environments supporting the cloud are becoming more stable.
Presently, with portability, and enormous information all assuming a not worthy part in how associations build up their IT and marketable strategies, it’s critical to comprehend the different cloud 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 developed component cloud offers IaaS which encourages to utilize machine assets in the cloud. You can design your machine as indicated by your need from the tremendous commercial center. You can choose machine picture write from Ubuntu, Amazon, Microsoft and so on., and can include CPU in cluster or parallel for satisfying your usage, pick strong state gadget memory(SSD) or HDD in view of your information input-yield speed et cetera. So dependably go for the correct one since this engineering would be the effectiveness mainstay of your association.
5. Storage as a Service
Cloud offers stockpiling administration to your application. Anybody can purchase from a little figure of 5GB to terabytes of capacity on the cloud from specialist organizations. It will likewise give the kind of capacity you need to purchase like a plate, SSD, IOPS SSD, and HDD.
What does Cloud Offer ?
Cloud offers strong administrations to utilize that are overseen by suppliers. It has apparatuses to improve business efficiency like Alexa, mail, which can enable you to set the need of assignments and develop your business. It gives devices to advancement, personality and access administration, CRM, security, and so forth. For databases, the cloud offers extraordinary administrations like reinforcement and recuperation, preview administration, and replication benefit. It additionally has an instrument for movement benefit in the event that you need to relocate your database to another specialist co-op. You can simply screen your assets in the cloud, and even set alerts and watch log documents. Cloudwatch is one such device for observing your machine.

Introduction
Increasingly, software companies are facing a dilemma as to the best delivery model for their business and many are opting for a “multi-delivery” model or multi-modal software delivery. A typical scenario is the vendor will offer the software both for installation on-premise and as an on-demand service. WordPress and Atlassian were early pioneers of this approach, with the latter offering products such as JIRA, Confluence and Crucible for both download and as a hosted solution. And on the big vendor front, Microsoft is pursuing a Software+Services strategy.
Private Cloud refers to IT capabilities are provided “as a service,” over an intranet, within the enterprise and behind the firewall. Privately owned and managed. The access limited to client and its partner network. The Private cloud drives efficiency, standardization and best practices while retaining greater customization and control within the organization. In a private cloud environment, all resources are local and dedicated. All cloud management is local.
Public Cloud refers to IT activities / functions are provided “as a service,” over the Internet Service provider owned and managed. In public cloud, access is by subscription.The public cloud delivers select set of standardized business process, application and/or infrastructure services on a flexible price per use basis. Multiple tenancy is a key characteristic of public cloud services.
Hybrid cloud is a combination of characteristics of both public and private cloud where internal and external service delivery methods are integrated. For example in the case of an Off-Premise Private Cloud, resources are dedicated, but off-premise. Enterprise administrator can manage the service catalog and policies. Cloud provider operates and manages the cloud infrastructure and resource pool.
Conclusion
private, public, hybrid or community cloud environment, planning will be the most important deployment step. During the planning phase, engineers and architects will examine how to build out their cloud environment and size it for future growth. By forecasting growth over a span of one, two and three years, IT managers can be ready for spikes in usage and be prepared for the growth demands of the business. This level of preparedness is called cloud growth agility. This means that the environment has been proactively sized and is ready to take on additional users as required by organizational demands.
