Public Cloud Hosting

By using the standard cloud computing model, public cloud host, a third party managed platform to make resources and services available to remote users around the world. Public Cloud resources usually include traditional IT infrastructure elements such as virtual machines, applications or storage.

The services can usually include a series of workloads including databases, firewalls, load balancers, management tools, or SaaS elements. Users can then assemble resources and services to build an infrastructure which is capable of deploying and operating big enterprise business.

The public host services are usually provided free or offered through a variety of subscription or on demand customization. Every option is available for you.

The main benefits that public cloud offers us is:

• The organizations can invest in and maintain their own on premises IT resources.
• It is scalable enough and quickly meets workload and user demands.
• It helps in fewer resource wastage, and customers pay as they use.

How does the Public cloud work?

Public Host is known to be an alternative approach to traditional on-premises IT architectures. When using a basic public cloud computing model, there is a third party provider host, an on-demand IT resource that delivered to the users over a network connection. This can either be over a public network or a dedicated network. Public cloud computing also called utility computing. In utility computing, the computing capabilities are delivered to users on demand, for example any other utility such as water, gas and telecommunications.

The public cloud model known for many different technologies, capabilities, and features that make it one of the best versions ever. These are some of the characteristics of public cloud:

• Self service provisioning
• ‘Pay for what you use’ pricing
• Measured service
• Broad network access
• Security
• Reliability & availability

The public cloud provider provides the infrastructure that is needed to the host and utilizes workloads in the cloud. It also offers tools and services that help customers manage cloud applications for example data storage, security, monitoring etc.

Migration to the Public Cloud

To migrate from on premises facilities to public cloud, you might want to seek the Myriad Factors. For instance, there are some organizations that might require support for diverse workload types that data centers are unable to provide. Now there are many factors that need to be considered like cost considerations, less overhead, lower maintenance requirements etc.

After choosing a provider, the IT team needs to select a cloud migration method that helps in moving data and workload into the provider’s cloud. In the offline migration process, the IT team needs to copy local data onto a portable device and then physically transport that hardware to a cloud provider. The online data migration occurs via network connection over the public internet or a networking service of a cloud provider.

Offline migration usually costs less and is faster when we know the amount of the data to transfer is significant. Online migration is usually a good fit for organizations that won’t move high volumes of data.

Organizations can also move their existing on-premises applications to the cloud, and there are a few different ways to do it. One of the initial methods is the lift and shift method that moves the application as it is without any redesign. Even though this approach is fast, it is highly prone to complications. One of the most common complications will be that the application might not perform properly within cloud architecture which can result in more cost that it must have remained on the premises. As a substitute, the IT teams can refactor on-premises applications ahead of the migration. Refactoring requires more time and planning. However this method will ensure that the application will function more effectively on cloud. An alternative option can be to rebuild your cloud native application entirely.

No matter what strategy you choose, there is a range of cloud native and third party migration tools that help you to manage the move to the public cloud.

Public Cloud Architecture

A public cloud is a highly virtualized environment that is usually depended on a high bandwidth of network connectivity which allows us to have access and exchange data. Providers have a multi-tenant architecture that allows users also referred to as tenants to run workloads on shared infrastructure and then use the same computing resources. In the public cloud, each tenant’s data and workload is logically separated and remains isolated from the data of other tenants. The providers are supposed to manage the cloud services in logically isolated locations within cloud regions. These locations are often called as availability zones that typically involve two or more connected and a highly available data center. Cloud resources can be replicated across multiple availability zones for redundancy and protection against outages.

You can further categorize Public cloud architecture on the basis of service model. The three most common service models are:

• IaaS: A third party provider that hosts infrastructure components for example server, storage as well as virtualization. The IaaS provides you with virtualized computing resources, for example Virtual Machines, over the internet or through dedicated connections.
• PaaS: A third party provider that delivers the hardwares and software tools. It is usually those needed for application development, including OSes to its users as a service.
• SaaS: A third party provider that hosts applications and makes them available to the customers over the internet.

The service model is responsible for how much control the user has over certain aspects of the cloud. For instance, when it comes to IaaS deployments, cloud customers create Virtual Machines, install Operating systems and manage cloud networking configuration. However in the IaaS and PaaS models, the provider fully manages the cloud networking architecture.

Except for the three main service models, a function as a service (FaaS) model further compliments cloud infrastructure and resources. The customers that create microservices, it turns out to be particularly useful for them. Based on serverless computing, it is a mechanism that breaks workloads into small, event driven resources components, and runs the code without managing the Virtual Machines. When triggered on demand, this allows organizations to execute code based tasks. This way the components only exist only for as long as the assigned task is running. The provider handles all the underlying cloud server maintenance when it comes to all the other cloud server versions.

Companies can also choose storage as a service provider in the public cloud. The cloud provider delivers a storage platform which further offers bare metal storage capacity, object storage, file storage, block storage, backup and archiving.

Benefits of Public Cloud Hosting

It is very important for an enterprise to be aware of the benefits that it offers. Moreover, your requirements and the benefits should be directly related to each other.

• Introduces new technologies: You get direct and early access to the IT industry if you as an organization use large cloud providers. It connects you to the IT industry’s latest technologies. This ranges from automatically updated applications to machine learning and Artificial Intelligence. There are many cloud customers that lack resources to have such access on their own, typically because the business might lack money or expertise to implement such capabilities.
• Unlimited Virtual Scalability: Public cloud manage to achieve a high redundancy and availability due to the providers various logically separated cloud locations. Cloud Capacity and resources increasingly expand and meet the user demands and fulfill traffic. Despite massive redundancy and availability, public cloud users receive a faster connectivity between cloud services and provider’s network. However because of bandwidth, latency issues are still quite common.
• Flexibility: Users may store large amounts of data and simply retrieve it because to the scalable and flexible nature of public cloud services. For disaster recovery, which involves backing up data and apps in case of emergency or outage, many enterprises rely on the cloud. Although it may be tempting to keep all data permanently, users should establish a data retention strategy that periodically deletes old data from storage to save money and protect privacy.
• Analytics: Organizations should collect valuable metrics on the resources they utilize and the data they store. Another advantage of doing so is cloud data analytics. Public cloud services can analyze resource and service usage to identify cost and utilization trends for more insightful business decisions.

Access to the dependable infrastructure of the provider and the abstraction of overhead administration activities are two further advantages of public clouds. These allow IT workers to concentrate on jobs that are more crucial to the company, including writing application code.

Challenges

No matter how strong the advantages might be, it is very important for organizations to do in-depth research about the challenges as well.

• Running Costs: When dealing with complex cloud host models we often have to deal with the costs and pricing that comes along with the installation and management. The cloud often costs less than the on premises option, however due to lack of knowledge organizations tend to pay more than required. Because of this slight issue, using and maintaining a cloud host has become even more difficult.
• Scarcity of cloud experts: Less skilled and unprofessional IT teams in your business can be one of the trivial reasons why it is difficult to operate a public host. Often companies are unable to hire well skilled people in IT. Because they lack expertise, companies tend to be ill equipped to solve the complexities of modern IT technology.
• Limited transparency and controls: There can be several issues which might be connected all together. Users of public clouds must also accept a limited degree of control over their IT infrastructure because the provider determines when and how to manage configurations. Other difficulties with the public cloud include concerns with data segregation brought on by multi-tenancy, latency problems for remote users, and adherence to regional and national legislation.
• Vendor Lock In: Despite the fact that each public host provider somewhat provides the same resources and services, the controls and assets can vary slightly. This makes it difficult for one data set or application to migrate easily between other providers. Hence, this can cause a major risk of vendor lock-in which will automatically increase the cost and limit capabilities.

Public cloud pricing

Pay-per-use, or PAYG, billing is the norm for public cloud pricing, meaning users only pay for the services they really utilize. Since an organization no longer needs to buy and maintain physical equipment for those areas of its business that it delivers to a public cloud IaaS, in many circumstances this helps lower IT expenses. Additionally, instead of treating public cloud expenses as capital or fixed costs, a business can classify them as operational or variable costs. Due to the fact that these operational spending decisions often necessitate fewer time-consuming evaluations or budget planning, this might give the organization more flexibility.

However, besides all the precautions it is very easy to overspend when it comes to clouds. When choosing which version, always remember to tally the benefits and your requirements. It is very important for you to do your own research before making any decision.

Public cloud security

Security has always remained the prime concern for businesses and enterprises. As a public cloud host, your user would definitely ask for a strong security system. Organizations that have access to sensitive data will expect you to provide them with a secure network as a priority. Even though public cloud providers offer you various security services. Security will also depend on the efforts put in by both the provider and customer.

To protect applications hosted in the cloud, organizations need to be aware of the many issues with cloud security. The public cloud needs to be protected from internal security risks like improperly configured resources and access management policies as well as external threats like malicious attacks and data breaches.

Security in hybrid clouds comes with its own set of difficulties. Data security in transit via public networks and networking components for diverse contexts are challenging issues that call for additional security measures like encryption.

Conclusion

Public cloud host seems to be a good option for your business. However, it also depends on your business requirements. Providers will try their best to offer you everything that you want, still as a user it is your duty to compare the basic information as well as compare prices and ask for customization.
