Cloud has revolutionised how individuals, businesses, schools and organisations use and access digital technology. Instead of buying and running all these servers, all these storage devices, software applications, and networking components locally, it’s possible for users to access computing resources on the internet whenever they want. This has made technology more flexible and attainable for any organization to expand or shrink computing requirements without the need for massive investments in the physical infrastructure.
Because cloud services can be used to store personal files, host websites, run business applications, analyze data, and communicate with customers, to name just a few, they can be used to support everything. As amazing as cloud computing is, it has its own problems. There are several aspects to take into account before an organization decides to migrate critical workloads to the cloud, including security, Internet reliance, service interruptions, vendor lock-in, and recurring subscription fees. It is therefore critical to understand the pros and cons of cloud before making decisions on cloud adoption.
Cloud Computing definitions.
Cloud computing is the provision of computing services and resources via the internet, without users having to maintain all the hardware components themselves. These can be servers, databases, storage, network, software, processing power, and development platform. Customers usually pay based on the resources or services they consume, and cloud providers host their own large data centres with the required infrastructure to provide these services.
Examples of common cloud service models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), with varying levels of control and responsibility. For instance, a company could lease virtual rather than physical servers, or another organization could utilize an online productivity application without having to install it on every computer. This model provides the user access to technology but requires them to deal with only a part of the physical aspects of the technology.
Major Benefits of Cloud Computing
One of the reasons why many people and companies from various industries are using cloud-based services, is the benefits of cloud computing that they offer. Compared to the traditional infrastructure, cloud technology can make computing resources more accessible, more scalable, more manageable and more updateable. The organizations don’t need to buy and install new hardware equipment before scaling up and can react to demand changes faster. Staff can also access applications and files from multiple remote locations, helping to facilitate remote and hybrid working arrangements.
Companies can cut down on some of their upfront infrastructure costs by opting for usage-based or subscription-based services. These features may also help to keep software up to date, improve data backup, facilitate collaboration, and provide disaster recovery, all of which can be easier with a cloud platform. But, the benefits are not to say that cloud computing is necessarily the right answer for every enterprise. The advantages will vary depending on the workload needs, security requirements, internet connectivity, cost, compliance needs, and dependability of the provider chosen.
1. Scalability
Cloud computing is highly scalable. In some instances, traditional IT infrastructure may necessitate that an organization make a guess at their future needs, and buy up the required hardware. This can lead to either under capacity during high traffic times or to over capacity when there is low traffic. Cloud computing offers a more flexible option as the organization is able to scale up or down its computing needs as it sees fit. For an online business, for instance, they might require a lot more processing power and storage during this big sale period than they do during a regular business day.
Cloud services can be used to provision more resources when they’re needed, and less when they’re not, if necessary. This can be extremely helpful when the business grows, for seasonal activity, when there are unexpected traffic demands, or when the business needs to change.
2. Flexibility and faster deployment
Cloud computing offers more flexibility to organizations on access to and use of technology. Teams may be able to provision cloud resources through a provider’s management platform much faster without having to wait for physical machines to be bought, delivered, installed, and configured. The developers can build testing environments, businesses can deploy apps, and organizations can grow storage space without having to go through the tedious hardware buying process first. For businesses that are trying out new products or services, this flexibility can be especially beneficial as they can try out various concepts without making the initial investment in significant physical facilities.
Cloud platforms can also enable access to various technologies such as databases, analytics, AI services, application development platforms, and networking. This means that organizations can change their technology environments as priorities change without being constrained by the hardware that they bought a few years ago.
3. Remote Accessibility
One of the other benefits is remote access. Applications and data in the cloud can frequently be used from various locations from a device with an internet connection and proper authentication. This is especially relevant with the increased uptake of remote and hybrid working options. They would be able to gain access to business apps, paperwork, communication systems and shared resources from home, on vacation, or in a different office location.
Learners could also access the same educational resources from remote or distant sites, and companies could have geographically dispersed employees access the same digital content without needing to be in the same physical space. While remote access offers greater convenience and continuity, the need for reliable Internet access and robust account security has never been greater. Organizations must therefore have suitable authentication, access control, device security and policies to make remote access helpful and secure.
4. Cost Effectiveness.
Cloud computing has the ability to improve cost efficiency which in turn changes how organizations approach IT resources. In the past we saw traditional infrastructure which often included large upfront investments for servers, storage devices, network equipment, software licenses, data center development, maintenance, cooling and power. What we found is that with the cloud model organizations do not have to make as many of these direct investments as the provider is the owner and operator of most of the base infrastructure. Also based on the service and use model an organization may pay for what they use or through a monthly subscription.
This in turn makes it easier for small companies to get their hands on technologies which may have been out of reach in the past in terms of purchase and maintenance. Also in the cloud model we see that some maintenance is done by the provider which in turn reduces that responsibility for the organization. That said cost savings are not a given. We see that organizations which do not pay attention to their use may see their cloud bills go up due to unused resources, excessive storage, premium features, data transfer charges, and unused subscriptions which in turn can greatly increase the bill over time.
5. Enhanced Cooperation.
Cloud based computing which puts at ease the issue of collaboration by which many authorized users are able to access shared applications, documents, databases and other resources. As against the past where we used to see files stored in individual computers, teams now have at their disposal information which is hosted centrally which in turn is accessible from any location. Also this may reduce what we used to see as some of the issues related to exchange of document versions via email or physical storage devices. Also we see that cloud based collaboration platforms may include features such as shared editing, comments, permissions, version history and real time communication.
These features in turn support teams which may be geographically dispersed across different offices, cities or countries. Also we see that in the academic world these services may be used to have students and teachers share in assignments and learning materials. But still for effective collaboration we see that we still require proper permissions and that goes hand in hand with organizational policies. That which we term as proper access control which is very important in order that shared cloud resources do not get into the hands of people who are not supposed to have access to it.
6. Automatic Updates and Support.
Cloud services can have the effect of reducing what customers put in terms of software and infrastructure maintenance. In many cloud settings the provider is responsible for the base hardware and may include in that what they do software updates, patches, infrastructure improvements and other maintenance activities which depends on the service model. Also it saves IT teams time as they do not have to go in and do all that manual work of updating each physical server or installing software improvements. Also automatic updates can get organizations access to new features and security improvements without the purchase and deployment of a totally new infrastructure.
That said organizations should know what the provider includes in what they manage and what is still the responsibility of the customer. Some cloud services still require customers to do application configuration, account management, some updates, or data protection. So while cloud computing does reduce the amount of maintenance it does not do away with the need for good IT management.
Potential Disadvantages of Cloud Computing
Although there are many benefits of cloud computing it is also true that organizations must pay attention to what it has to offer. We see that migration to the cloud changes the location of infrastructure and how technology is managed but it also does not get rid of operation risk. What we do see is that some responsibilities transfer from the user to the cloud provider and some trained by the user. Also security, availability, connectivity, pricing, data management and provider dependence are issues which play a role in the success of a cloud strategy.
A company which picks a cloud platform without looking into these issues may run into unexpected cost or operation problems down the road. Also cloud computing should be looked at as a business and technology decision and not just a way to get rid of physical servers. Also before choosing a service organizations should look at the value of the data which is involved, the results of service outages, regulatory issues, expected use, what are the recovery options and also what is the long term relationship going to be with the provider.
1. Security Issues and Privacy.
Security is a top issue in cloud computing. In cloud environments we see very important business info, personal data, financial reports, intellectual property and others which are of great value, thus making them very appealing for cyber attacks. While large scale cloud players put in great effort into security of their infrastructure which is a plus point for the users to go with a reputed player, it is not a full proof protection for organizations.
We still see issues like weak passwords, stolen info, improper storage config, over wide permissions, vulnerable apps, and poor in house security practices that leave cloud resources at risk. Also what an organization puts in terms of data storage, processing and protection also plays a role. Also with data privacy and regulation issues which may see data stored and processed in different countries we have more to think about. For all these reasons strong auth, access controls, encryption, monitoring, staff awareness, and proper security policies are a must even when the base structure is out of house.
2. Reliance on Internet Connectivity.
Cloud based services are very much a function of network connection which is mostly via the internet. Should a business have an internet down time it is the users which may be left out of important applications, files, databases, or communication tools. This in turn may cause great operational issues for companies which are heavy users of cloud services for day to day functions. Also what we see is that connectivity may be an issue of slow speed networks, failed infrastructure, local outages, or issues with telecommunication providers.
This issue is very much present in areas which have unreliable or expensive internet infrastructure. Some applications do provide for offline use which is a plus, but that doesn’t solve the issue for services that require constant online access. What we recommend is that organizations do a due diligence of their network reliability before they migrate critical work loads to the cloud and also to put in place redundancy, backup connection, offline procedures and disaster recovery plans where it makes sense.
3. Downtime and System Access.
Cloud providers put in place their infrastructure to achieve high availability but we must note that no technology service is to blame for outages which will eventually happen. We see hardware failures, software issues, config errors, network incidents, maintenance outages or other unforecasted events which do play out to affect cloud services. If a company is to run a key business process on a single cloud service they are too great a risk outages may put access to important systems out of action for employees or customers.
That which results may range from a minor issue to large scale financial and operational disruption based on the service affected. Thus it is to the company’s benefit to look at a provider’s service level agreements, reliability record, backup solutions, recovery options and incident management processes before they go live with a critical service. Also companies may reduce risk by designing systems with redundancy in them and to also have proper backup plans in place instead of the assumption that cloud hosting is a full proof solution against down time or data loss.
4. Proprietary Platform Tie-In.
Vendor tie-in is a situation in which a company which has grown to depend on a certain cloud service provider will find it a hard, expensive and technical challenge to transition his services over to another provider. Cloud platforms include built in special services, management solutions, databases, application access, that on many occasions do not have equal counterparts at other providers. As an entity grows to use and design their systems within the given environment of the features provided they will see very large scale issues with a switch out of providers’ that will require very in depth and large scale changes.
Also we see data transfer costs as well as differences in platform that also play a role in this. Vendor lock in does not in fact make cloud a bad idea but it is a key issue in the strategy. What companies can do is to look at what is the level of portability they need before they go ahead with the deployment, use open standards when practical, keep very good documentation of their systems, and also avoid to the greatest degree possible the use of proprietary services if flexibility is high on the priority list.
5. Continuous and ongoing subscription and usage fees.
Cloud computing does see a reduction in upfront infrastructure spend but at the same time introduces ongoing subscription and usage costs. We see that as different from a physical piece of hardware that is bought out and which may serve a few years’ use; cloud services will charge on a recurring basis for computing power, storage, databases, software licenses, data transfer, backup, monitoring, and add on features.
Also these charges can add up if the business does not pay attention to what they are using. For instance we have seen unused virtual machines, too much storage, over use of premium services, or apps running when not required which can blow out the monthly bill. Also the pricing models in cloud can be very complex so that it is hard for companies to do a long term cost analysis without doing in depth study. Thus effective cloud cost management includes in its regular monitoring, resource optimization, budget setting and clear guidelines for what is put into the cloud and what is removed.
How to determine if Cloud Computing is right for you
Choosing what to do with cloud computing should be based on what best fits your organization’s needs, not on the tech’s popularity. First, businesses should identify which processes will flow from the cloud and which may do better on local infrastructure. To that end data sensitivity, application performance, regulatory issues, network reliability, growth expectations, technical skills, and budget should all be taken into account. Also it is to0 important to look at total cost of ownership which includes not only the initial price of a cloud service but also others.
Things like subscription, migration, training, security, data transfer, support and future scale should be looked at. Also it is a good idea to test a service with a small set of workloads before fully going in. That way you can see technical, financial and operational issues. A careful hybrid approach may at times be a better solution then going completely to the cloud.
Conclusion
Cloud computing presents an excellent option to what we have traditionally known of as IT infrastructure which in turn gives companies greater scale, flexibility, remote access, collaboration, and the use of modern tech. We see that it reduces some of the initial investment in infrastructure and at the same time simplifies some aspects of software and hardware maintenance which in turn makes advanced computing features available to a wider range of company sizes. At the same time we see that adoption of cloud has its issues which must be taken into account. Issues like security and privacy, dependency on internet, service outages, vendor lock in, and the issue of ongoing subscription costs which in turn play a role in the dependability and financial return of a cloud based strategy.
The best way out is to not assume that cloud computing is for all and in all cases better than traditional infrastructure but to do a case by case analysis of where it truly adds value and where its shortcomings present an unacceptably high risk. By looking at the pro’s and con’s of cloud solutions companies can choose which services best fit their operational needs, security requirements, budgets and long term tech goals.
