What is Amazon Cloud

What is the AWS Cloud?

Amazon Web Services (AWS for short) is one of the leading cloud computing providers worldwide. We present the diverse components of the AWS cloud as well as the main advantages and disadvantages of this public cloud.

How does Amazon AWS work?

AWS, a subsidiary of Amazon.com, is a comprehensive platform for cloud computing services. Cloud computing usually includes the three components Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). Or to put it simply: Instead of operating their own servers or data centers, customers here obtain IT infrastructures and services as required and do not have to worry about maintenance and updates of the underlying hardware and data centers.

According to their own statement, AWS offers significantly more services with a larger range of functions compared to other cloud providers. This includes infrastructure solutions such as compute resources, storage and databases as well as solutions for current trends such as machine learning, artificial intelligence or the Internet of Things. AWS would like to offer its customers the possibility to switch to the cloud quickly and easily and to be able to map all digital projects there. AWS also offers numerous databases that the cloud provider developed specifically for specific applications.

What does AWS cost?

The provider provides a price list for its services. The actual costs for the user then depend on the individual consumption. On the one hand, this is an advantage, as customers remain flexible at all times and can adapt their resources to requirements. On the other hand, costs can easily get out of hand if consumption is higher than previously expected. For this reason, it is advisable to keep an eye on it at all times. Alternatively, companies can use the services of a managed AWS partner who will support them in designing and operating their cloud solution at Amazon.

What is AWS Cloud Computing made of?

AWS users get access to a complete ecosystem of computing power, storage, software and services. The most important services include:

Cloud server: AWS users can access virtual server (= EC2, Elastic Compute Cloud). Linux distributions or Microsoft Windows are available as operating systems. Billing is based on the duration (by the hour or by the second), the memory used or the compute units.

Storage space: Companies can theoretically store any large amounts of data via AWS and only pay for the storage space they use. The storage takes place via the in-house storage service Amazon Simple Storage Service (AWS S3), access via HTTP / HTTPS.

Network: The content from AWS services (e.g. EC2 or S3) is sent via CloudFront, one Content Delivery Network (CDN), provided. The global distribution reduces the access time. In addition to individual files, depending on the configuration, entire domains can also be provided, SSL-encrypted if desired.

Database services: With SimpleDB and Relational Database Service (RDS) there are two different virtual databases to choose from, whereby the former is more intended for "simple" storage. The RDS virtual database is based on MySQL, Microsoft SQL Server or Oracle.

Development tools: From development to analyzing, debugging and testing to deployment, AWS has all the tools developers need.

AWS Marketplace: A constantly growing selection of software made available by independent providers. Here are also numerous applications from the areas IoT, AI or Big Data to find.

What are the pros and cons of the AWS cloud?

Without a doubt, AWS is one of the most popular providers of cloud computing services. Current figures show that despite increasing competitive pressure, for example from Azure, AWS is still at the forefront of the public clouds. But why is AWS so popular? And are there any disadvantages? We have summarized the most important facts for you:

AWS benefits

+ Cost efficiency: AWS is considered to be quite cheap, and you only pay for the services that you actually use. Previous investment costs are completely eliminated.

+ Availability: To implement new ideas, your development team can directly access the services and thus react quickly to changes in the market, for example.

+ Network: The AWS Cloud is currently available in 54 Availability Zones within 18 geographic regions. Due to the short transmission paths, latency times are low.

+ Selection: AWS users can access a wide range of services that are continuously being developed.

+ Flexibility: Capacities can be flexibly added or removed at any time. This enables agile and scalable action.

AWS cons

- Orientation: The wide range of services can be a bit overwhelming.

- Consultation: AWS hardly offers any consulting services, especially for small and medium-sized companies. However, it is possible to use external managed AWS cloud service providers such as plusserver or consulting companies. Together with their customers, they work out an optimized strategy for using the cloud.

How do companies use an AWS cloud?

Public clouds are useful for companies, for example, in order to be able to develop individual applications quickly and easily without having to purchase their own product licenses or server space. In other words: AWS provides developers with a customized and reliable IT infrastructure on demand (= self service).

In addition, shop systems or applications such as WordPress or other content management systems can run on AWS. Automatic load overflow from your own IT to the public cloud is also a common use case to ensure the availability of a website even with high traffic. In addition to the immediate availability, the flexibility and the wide range of services, the cost efficiency can speak in favor of using AWS, provided that the above points on costs are observed.

What about security and compliance at AWS?

Since the data centers are operated by Amazon and the user usually does not know in which region the services are booked, AWS is repeatedly confronted with the issue of data security. It is not for nothing that the company advertises on the website with security certifications, encryption, hardware security modules and much more. In addition, according to their own statements, compliance is very important to AWS and, for example, identity checks are carried out.

For particularly sensitive projects or data storage in Germany specified by the company, however, it may be advisable to use a hybrid cloud that includes both AWS and other infrastructures that are operated in Germany. Sensitive information can then be stored in the known environment. A data exchange is possible at any time without any problems via the appropriate interfaces.

With the European multi-cloud platform plus.io, such hybrid cloud solutions can be easily implemented, for example. It provides secure connections via the hybrid connector and central management of all cloud resources.

Who Needs a Managed AWS Cloud?

Hundreds of thousands of customers already trust AWS Cloud Computing for the rapid implementation of innovative developments and functions. Ideas can be implemented very quickly and, above all, with low risk (finances, resources). For this it is not absolutely necessary to build up in-depth cloud expertise in your own company. Managed public cloud providers support companies in determining the optimal cloud resources for their specific needs, planning the setup and migrating the applications. In later operation, external service providers also take on management and support.
