Cloud Computing

Imagine you have a brilliant idea for a software application. But before your vision can become a reality, you face a host of challenges: expensive servers, endless storage space requirements and a dedicated network team. Sounds like a nightmare, right?

Luckily, there’s the cloud.

But what exactly is the cloud? Simply put, it’s the magic you need to manage your IT infrastructure over the internet. No more bulky servers in the office, no more stress over limited capacity. The cloud offers you everything you need — flexible, scalable and cost-efficient.

In this blog post, we will guide you through the wonderful world of cloud computing. Find out how you can access your data from anywhere, reduce IT costs and increase productivity. Let’s explore the different cloud models and their applications that can revolutionize your business processes.

1. What is a cloud?

Suppose you develop an innovative idea for a software application. To implement it and be successful, you need servers, storage space, development, dedicated network and application security.

Providing all this support can be expensive, time-consuming and risky.
All of these problems can be easily solved with the help of the cloud.

But what exactly is a cloud? Cloud or cloud computing is the provision of computer services such as servers, storage space, databases and networks over the internet.
It is a new way of working and managing data that allows you to access your data and applications from anywhere.

2. Advantages of cloud computing

Without the cloud, companies are reliant on on-premise solutions.

They have significant challenges and limitations such as

  • Hardware limitations and higher operating costs;
  • Dependence on the physical capacity and location of resources;
  • Downtime, data loss, compatibility and compliance;
  • Impairment of the quality and reliability of services and products;

With the help of cloud computing, companies can benefit from the following advantages

  • Lower IT costs;
  • Centralised data security;
  • Scalability;
  • Flexibility;
  • Automated updates;
  • Rapid deployment;
  • Instant business insights and continuity;
  • Collaboration and communication;
  • Increased performance and availability;

3. Cloud services & deployment models

Cloud providers offer different types of provision and services.

Cloud service models:

  • Software-as-a-Service (SaaS): e.g. Slaesforce, Slack;
  • Platform-as-a-Service (PaaS): e.g. Microsoft Azure;
  • Infrastructure-as-a-Service (IaaS): e.g. Google Compute Engine, OpenStack;
  • Function-as-a-Service (FaaS): e.g. Google Cloud Functions;

Cloud deployment models:

  • Private cloud: In the private cloud, services such as servers, data centre or distributed network are completely reserved for one company.
  • Public cloud: In this deployment, cloud services are shared by several organisations.
  • Hybrid cloud: In hybrid cloud deployments, public and private clouds are combined.
  • Multi cloud: This is a type of cloud deployment in which several public clouds are used.

4. Cloud technology & examples

The best-known providers of cloud computing are Amazon Web Services, Microsoft Azure and Google Cloud. However, the cloud comes in various forms and technologies:

  • Online storage: Microsoft OneDrive, iCloud;
  • E-mail: iCloud Mail;
  • Smart watches / fitness trackers: Apple Watch, Fitbit;
  • Streaming platforms: YouTube, Netflix;
  • Online word processing: Google Doc;

5. Problems & challenges of cloud computing

Although cloud computing can have many benefits for businesses and development teams, it can also present some issues and challenges that organisations should be aware of in order to achieve the best outcome.

5.1 Internet connectivity

Most cloud-based programmes cannot be used if there is no internet connection. Companies need to invest in higher bandwidth options and focus on improving operational efficiency to minimise reliance on network capacity.

5.2 Ownership & limited control

As the cloud infrastructure is built, maintained and managed entirely by third parties in remote locations, end users have less control over the function and execution of the services. So before deciding on a cloud provider, you need to ask yourself: What data does the cloud service process? What functions does the cloud service offer? What does the contractual relationship look like?

5.3 Security & Privacy

Not all cloud solutions are equally secure. This is especially important when it comes to off-site storage of important or private data. Before entrusting critical aspects of your IT or data to third parties, it is important to apply some security guidelines, such as configuring network hardware and installing the latest software updates to close potential security gaps.

5.4 Performance problems

The effectiveness of cloud solutions depends heavily on providers offering their customers appropriate services. For example, a sudden outage of a cloud provider can have a significant impact on the business. Organisations need to select providers that implement proactive SaaS monitoring standards in real time.

5.5 Insufficient knowledge

Organisations need experts to manage infrastructure effectively. Companies need to hire professionals who specialise in DevOps and cloud engineering as workloads continue to increase and the market experiences a surge in the adoption of new tools.

5.6 Reliability & availability

The scarcity and unreliability of individual services is a major challenge for cloud computing. Therefore, organisations must seek additional resources to meet evolving business needs and be assured of the reliability and availability of the cloud provider.

5.7 Ineffective cost management

Cloud providers offer a subscription model where you pay for the services you use. However, these costs can accumulate over time. It is better for companies to check their systems regularly and use tools to monitor resource utilisation.

6. Conclusion

Cloud computing offers a modern solution for organisations by providing cost-effective, scalable and flexible IT resources. The benefits, such as centralised data security, rapid provisioning and improved collaboration, make it an attractive option, despite challenges such as internet dependency and limited control.

With various models — from private and public to hybrid and multi-cloud, as well as service options such as SaaS, PaaS, IaaS and FaaS — companies can choose the solution that best suits their needs. A thorough examination of security and data protection aspects as well as effective cost management are essential in order to fully utilise the benefits.

Cloud computing is a key driver of digital transformation and increased efficiency in companies.
