Cloud computing, today and tomorrow 

Cloud computing originally refers to a network with several computers, but that is long gone, let alone for the latest generations, X, Y, Z. 

Most conversations about "the Cloud" refer to public Clouds, where different organizations share Cloud resources in a data center owned by a Cloud provider such as Amazon, Microsoft or Google, for example. These organizations are also referred to as "Hyperscalers. (W.org; "the ability of an architecture to scale appropriately as more demand is added to the system.") 

This typically includes the ability to flawlessly provision and add compute, memory, network and storage resources to a particular node or set of nodes that together form a larger computing, distributed computing or "grid computing" environment.

Hyperscale computing is needed to build a robust and scalable cloud, big data, or distributed storage system and is often associated with the infrastructure needed to run extremely large sites such as Google, Facebook, Twitter, Amazon, Alibaba, Microsoft, as well as HUAWEI, IBM Cloud, or Oracle.  

Differences 

The major difference between public and private Cloud is that a private Cloud is used exclusively by one organization, which usually means that the resources for the computing systems and support, are located at that organization's own location and offices. 

Practically everyone understands that fundamental distinction between these Cloud types, but sometimes people use the term private Cloud because they don't understand the basic definition of Cloud computing. To qualify as Cloud computing, any Cloud model (a public, private or hybrid model, no matter which it is) must first meet the 5 criteria of Cloud computing:  

  • On-demand self-service 
  • Resource pooling. 
  • Fast elasticity, scalability 
  • Measured service 
  • Wide network access 

And just because you have multiple local computers on a server does not immediately mean you have a private Cloud.   

Why should you use Public Cloud? 

Young people, especially generations Y and Z are all using public Cloud solutions whether it is for mobile services or, for example, storage from the desktop and applications for workplace support, CRM, Marketing, Lead Generation, you name it. They do this out of convenience and low investment, through monthly subscriptions with relatively low costs. 

In larger companies or public institutions with high demand for computing power to run different services, it can also be more effective to pool shared computing resources between different internal groups, thereby also reducing costs. 

In addition, a private Cloud can be a good solution for organizations that want the benefits of Cloud computing while maintaining control over data, since sensitive information often cannot legally be sent to a public Cloud provider, for example, with government agencies. Other organizations may be concerned about public Cloud security. With private Cloud, having internal computing resources is often more efficient than relying on an external public Cloud provider because the data does not have to travel far, for example, over the Internet, which can lead to bottlenecks without a very fast (and often expensive) connection. 

In a private Cloud, resource usage is measured and can be scaled depending on a department's changing needs, just as in a public Cloud. As a result, organizations sometimes even charge internal departments for computing resources, as a public Cloud provider would. This internal billing for Cloud resources is known as recovery. 

Because private Clouds reside in an organization's data center, they typically must be managed internally. However, there are some vendors that offer managed private Cloud services, where the operational and maintenance work of your Cloud infrastructure is handled to varying degrees by the Cloud provider.   

So what is hybrid cloud? 

Private versus public Cloud is not always a mandatory choice, of course. You can also start combining the best of both worlds. Hybrid Cloud is a model that describes when a public Cloud is connected to another Cloud type (such as a private Cloud) and there is data or application comptability between the two. So if you had two Web servers in a server room in your office and another 2 Web servers in Microsoft Azure and all 4 servers that could have load balance between them, that would be a hybrid Cloud model. And also if you could migrate a VM (virtual machine) running on a local Cloud infrastructure to a VM, from, say, Microsoft Azure or Wasabi, that would also be a hybrid model. 

To be clear, Hybrid Cloud does not just mean that you have some servers locally and some unrelated instances managed by a Cloud provider. It also means that interconnection and communication between the two systems is essential. Use cases for Hybrid Cloud solutions, include being able to quickly scale resources to the Cloud infrastructure to meet increased computing needs or synchronize data between two locations to ensure redundancy.

And of course scalability, which is practically the same as any other Cloud solution, only to be installed and maintained from within one's own organization and not just through a public Cloud service provider. 

Common Cloud: Unknown and unloved? 

A shared Cloud model, is a model with two similar organizations with shared concerns using the same Cloud computing resources. For example, if there is a group of 3 companies, with or without the same parent company, located in a geographically similar location, they could share resources with each other. This is also known as "community Cloud. 

Community Cloud thus moves between public and private Cloud. The model is not open for use by the general public, but at the same time it is not intended for use by a single organization. It allows organizations to save costs and learn from each other about the use of the applications they use from their shared Cloud and/or Cloud Service Provider. 

From Real Solutions Haarlem , we work with different solutions to set up a Hybrid or Community Cloud. If you want to do this from an existing private Cloud environment, you can activate Wasabi Hot Cloud Storage through us and thus add a Cloud environment to your own infrastructure. 

If you want to work from your existing Public Cloud account and do not yet have a solid infrastructure of your own, we recommend the NAS (Network Attached Storage) solutions from Synology and QNAP. These manufacturers have their own OS, which is compatible with the OS, of Microsoft, iOS, Google and Linux. They also both have the ability to easily collect data from the NAS to the Cloud and back, with or without automatic synchronization. 

With a NAS you easily realize your own Cloud environment and with additions like online backup, from the NAS manufacturer itself or for example Acronis Cyber Protect, which can also be activated through us, you then create a Hybrid environment. 

Transporting large amounts of existing data to the Cloud 

We have a great solution for this as well, namely Seagate Lyve Mobile. A data management platform, with which you can quickly and easily transport large amounts of data to the Cloud. (Cloud Ingest). There are several 'Mobile Array's available. These are data systems, similar to a large external hard drive, only much more secure, because your data on these devices always remains encrypted. You can only rent this solution, so you don't have to make high investments in new infrastructure. For capacities from 16TB up to 96TB (HDD) and 92TB (SSD), there are solutions, which in combination with a SAS Receiver, can upload up to 100TB per day super fast to a Cloud location of your choice. 

We arrange everything together with Seagate. A Mobile Array is sent to you or your end customer and once the data has been transferred from the local systems, the Mobile Array is retrieved and then Seagate, completely secure and AVG compliant, takes care of the Ingest in the Cloud. After verification, that you have controlled your data in the Cloud environment, the data on your Mobile Array is deleted again. You can use this for larger projects on location, temporary storage or as a permanent solution for regularly moving data from your own systems to the Cloud without burdening the local network. In addition, employees can work faster from the Cloud, saving time and money.
