The cloud computing brings undeniable benefits for all types of companies. They wish to enhance productivity, reduce costs and free themselves up from most complicated day to day IT management. But still, most companies concern about cloud security for their information from the cloud services providers. The benefits of cloud computing are more than just reducing cost, enhance productivities, cloud security, etc. You must know what really a business need to migrate to the cloud, and using cloud service. What are the important benefits of cloud computing for a business?

There is no doubt that online businesses can reap huge benefits of cloud computing services. However, with many advantages of cloud computing, still, most business owners count the cloud computing security as a drawback of cloud computing technology. This article focus on levels of cloud computing security for online small business and enterprise business.

Benefits of Cloud Computing

The Cloud computing offers your business many benefits. It allows you to set up what is essentially a virtual office to give you the flexibility of connecting to your business anywhere, anytime. With the growing number of web-enabled devices used in today’s business environment (e.g. smartphones, tablets), access to your data is even easier. There are many benefits to moving your business to the cloud:

Important benefits of cloud computing for a business: 

• Fresh Software
• Do more with Less
• Flexible Costs
• Increased Productivity
• Growth Management
• Location Independent
• Scalability and Mobility
• Sustainability
• Agile Development
• Easy and Secure Virtualization
• Faster Application Delivery
• Flexible Model
• Improved Business Continuity
• Rental Pricing Model or Pay-as-you-use
• Time-sharing Models
• Utility-based Computing
• Disaster Recovery

A short way to talk about the benefits of cloud computing and cloud security is just once using the cloud services.

Reduced IT Costs

Moving to cloud computing may reduce the cost of managing and maintaining your IT systems. Rather than purchasing expensive systems and equipment for your business, you can reduce your costs by using the resources of your cloud computing service provider. You may be able to reduce your operating costs because:

• The cost of system upgrades, new hardware and software may be included in your contract
• You no longer need to pay wages for expert staff
• Your energy consumption costs may be reduced
• There are fewer time delays.

Flexibility of work practices

Cloud computing allows employees to be more flexible in their work practices. For example, you have the ability to access data from home, on holiday. Or via the commute to and from work. If you need access to your data while you are off-site, you can connect to your virtual office, quickly and easily.

Access to automatic updates

Access to automatic updates for your IT requirements may be included in your service fee. Depending on your cloud computing service provider, your system will regularly be updated with the latest technology. This could include up-to-date versions of software, as well as upgrades to servers and computer processing power.

Scalability

Your business can scale up or scale down your operation and storage needs quickly to suit your situation, allowing flexibility as your needs change. Rather than purchasing and installing expensive upgrades yourself, your cloud computing service provider can handle this for you. Using the cloud frees up your time so you can get on with running your business.

Business Continuity

Protecting your data and systems is an important part of business continuity planning. Whether you experience a natural disaster, power failure or other crisis, having your data stored in the cloud ensures it is backed up and protected in a secure and safe location. Being able to access your data again quickly allows you to conduct business as usual, minimising any downtime and loss of productivity.

Collaboration efficiency

Collaboration in a cloud environment gives your business the ability to communicate and share more easily outside of the traditional methods. If you are working on a project across different locations, you could use cloud computing to give employees, contractors and third parties access to the same files. You could also choose a cloud computing model that makes it easy for you to share your records with your advisers (e.g. a quick and secure way to share accounting records with your accountant or financial adviser).

Cloud Security

Although the business convenience, economy, and enhanced workforce productivity have emerged as just some of the measurable benefits of cloud computing, cloud computing vendors provide high-level security for cloud computing data centers.

According to the recommendation of higher international organization for Standardization (ISO) standards for cloud computing security. The cloud computing is a multi-billion-dollar industry, and the business is based in part on cloud vendors’ ability to keep customers’ data secure. The standards they adhere to are designed for that.

One of the benefits of cloud computing is that “security is actually increased when using cloud solutions due to strict ISO security standards that cloud providers must adhere to, in addition to the regular security audits.” Another clear guide I recommend you to read more about ISO 27001 vs. ISO 27017 – Information security controls for cloud services by Dejan Kosutic.

Measures of Cloud Computing Security

The below 10 cloud computing security benefits that cloud computing providers offers for cloud security to hold you back from implementation.

10 Important Cloud Computing Security:

1. Fresh and anywhere secure accessible software.
2. High-level data encryption for sensitive information on cloud services.
3. Physical security monitoring of data center facilities.
4. Standardized and continuously monitored information security policy management.
5. Skilled, certified personnel to monitor, manage and maintain network infrastructure.
6. DMZ, using firewalls, intrusion detection, and prevention systems.
7. Background checks, security training.
8. Specialized threat identification and management.
9. Reduce human errors by using cloud computing technologies.

Anyway, in the ever-increasing era of data breaches, the cloud security solution has security protocols in place to protect sensitive information and transactions. This prevents a third party from eavesdropping or tampering with data being transmitted. So these are the plan for cloud security, despite your initial concerns about the potential security risks of cloud computing. You can consult with a cloud computing security expert.

When it comes to cloud computing infrastructure, the virtualized resources are hosted by an IT department or the service provider and delivered to the users over the internet or a network. Such resources include virtual machines as well as components including a computer, servers, network switches, memory, storage, firewalls, and load balance devices etc.

In cloud computing architecture that refers to the back end and front end of the cloud computing environment, cloud computing infrastructure is comprised of back end components.

Businesses utilize cloud computing infrastructures to run their applications. When compared to subscription-based pricing models and payment structures that enable the users to subscribe to the vendor services for a set price, the cloud computing infrastructure is usually bought with the use of a pay-per-use model. In the pay-per-usage model, users pay only for the consumed services, generally on a weekly, monthly or hourly basis.

Understanding the Cloud Services SaaS, PaaS, IaaS

Instead of purchasing cloud computing infrastructure from certain cloud computing vendors or provider, businesses may also build cloud infrastructure on-premises. Once cloud providers maintain cloud infrastructure, an environment is a public cloud. When organizations who use cloud maintains cloud infrastructure, an environment can be a private cloud. When both user and cloud provider own pieces of cloud infrastructure, an environment is known as a hybrid cloud.

Anyway, choose from the three types of cloud computing services that need you for your company and end-users.

These are three categories of cloud computing services, however, a very simplified way of differentiating these flavours of Cloud Computing is as follows;

• SaaS applications are designed for end-users, delivered over the web
• PaaS is the set of tools and services designed to make coding and deploying those applications quick and efficient
• IaaS is the hardware and software that powers it all – servers, storage, networks, operating systems

Cloud Computing Infrastructure Components 

Cloud computing infrastructure typically consists of storage devices, servers, cloud management software, network, platform virtualization, and deployment software.

• Hyper visor

It’s a low-level program or firmware that serves as a virtual machine manager. It enables anyone to share a single physical instance of cloud resources between some tenants.

• Management Software

It helps you to configure and maintain infrastructure.

• Deployment Software

It helps to integrate and to deploy the application on the cloud.

• Server

It helps to compute resource sharing and provides some services including de-allocation and resource allocation, providing security, and monitoring resources.

• Network

It’s the most important component in cloud computing infrastructure. It enables you to connect cloud services online. It’s also possible to deliver the network as a utility online, which only means that the customers may customize the network protocol and route.

• Storage

Cloud will keep different replicas of storage. If one of the resources for storage fails, it may be extracted from another one that makes cloud computing much reliable and efficient.

Infrastructural Constraints

Some of the constraints that cloud infrastructure must implement are below:

• Transparency

In cloud computing, one of the premises is that the services are transparently delivered whatever the physical implementation in the cloud. The transparency is a foundational concept in cloud computing. It’s actually another form of virtualization where various resources appear to the users as a single resource. It’s unlikely that single servers or resources will always be sufficed to satisfy the demand for a provisioned resource.

• Scalability

Scaling up application delivery solutions aren’t that simple as scaling up an app for the reason that it involves configuration or re-architecting the network. Therefore, an application delivery solution is required to be scalable that will require virtual infrastructure so that the resource can be de-provisioned and provisioned easily.

• Intelligent Monitoring

For you to achieve on-demand scalability as well as transparency required of mega data centre in the cloud, control nodes like application delivery solution will require intelligent monitoring capabilities. It’ll need to understand when a certain server is overwhelmed and once network conditions are affecting the application performance adversely. It needs to determine the services and applications being served from the cloud and understanding when behaviour is outside the accepted norms. While functionality may be implemented externally in a huge management monitoring system, once the control nodes see clients, the state of applications, and the network, it’s in the best position to understand real-time conditions as well as the performance of involved parties without the need of heavy lifting of correlation which would be needed by external monitoring systems.

• Security

Cloud’s mega data centre must be architect securely. The control node must also be secured. Read more about cloud computing security benefits for online business.

The Basics of Cloud Computing Infrastructure

Clouds may be private or public and provide some IT capabilities as a Service. With this in mind, what does cloud mean when it comes to infrastructure?

While the cloud services may vary in implementation detail, they share common cloud computing infrastructure elements and these include:

• Multi-tenancy and metering.

Another attribute of a cloud service is that this is consumed by several customers. Cloud management software and cloud computing infrastructure should support the ability to logically or physically segregate the data storage and traffic associated with various customers and to track service usage closely per customer so that the user may be charged for or reported on.

• Self-service interfaces.

A trademark of cloud solutions is that the users can invoke them through the web interface without the assistance of a service provider. Therefore, an important part of cloud computing infrastructure is support for the web-oriented service application programming interface. Usually, a web portal is made available to the service users and in some cases, the API is exposed to the service users so that they may establish their own apps that call API.

• Pervasive virtualization.

Without this and the ability to utilize pooled IT resources efficiently and flexibility, it is difficult to imagine cloud computing. Typically, cloud computing infrastructure uses network virtualization and storage and server virtualization.

• Pervasive automation.

To meet them instantaneously and unpredictable user demands, cloud solutions make use of software, which automates the scaling and provisioning of storage, networking resources, and compute.

Cloud Computing Infrastructure Is More Than a Data Center

An overlooked, yet critical dimension of cloud architecture is public internet. In many cases, end-users interface with cloud services through online and cloud service performance is susceptible to the internet’s inherent variability. It’s true even for the private enterprise cloud services if the users access the service through mobile devices or geographically dispersed.

Today, a lot of companies help private and public cloud operators deliver high-performing cloud solutions online to end-users connecting anywhere across the globe, from any kind of device.
