The environments in Cloud They are the trend of this era, that even with the emergence of COVID-19 saw an unprecedented acceleration in the adoption of digital. In response to this, IT departments seek to minimize the size of their companies' data centers, gaining flexibility, adaptability and scalability, while optimizing the availability of the flood of data they receive.
Most organizations opt for an architecture of hybrid cloud,
namely, incorporates a certain degree of management, organization and portability of workloads in two or more environments.

The global hybrid cloud market was valued in USD 61,26 billion in 2019 and is expected to reach USD 283,93 billion in 2027, growing at an annual rate of 22,8% of 2020 a 2027. Source: Verified market research |
It is therefore a complex architecture, with different systems and some challenges to face such as connectivity, scalability, visibility and control.
But, What, when and why to use a hybrid cloud solution in your company?

Why use hybrid cloud today?
There are three main use cases where such configuration benefits a business:
1. Cost optimization
Hybrid cloud enables customers to deploy applications in the appropriate cloud based on application characteristics. Let's see some characteristics of the application and the most suitable cloud for that type of application.

FEATURES OF THE APPLICATION |
EXAMPLE |
MOST SUITABLE CLOUD |
|
Ephemeral |
A single great calculation |
Public |
|
Very elastic |
Seasonal online business |
Public |
|
Small scale with geographic diversity |
Web application for a startup |
Public |
|
Consistent, long life |
Test and development workload |
Private |
|
You need low latency and high performance |
Business applications, VDI (virtual desktop infrastructure) |
Private |
|
Local workload need |
Tightly coupled multi-tier application |
Private |
|
Need for more control over users, budget |
Self-service cloud for higher education |
Private |
|
Need for integration with local devices or data |
I + D on internal data |
Private |
|
Need for data security and compliance |
Finance, ERP, HR apps |

Some apps fit into more than one category. For instance, if you have an elastic app that requires a local workload, you may have to sacrifice locality and run it on a public cloud.
2. Big workloads
Many companies are cyclical in nature and their scale of application and infrastructure requirements can vary dramatically from month to month.. You can run your base workload on local infrastructure and scale in a public cloud to meet peak demand.
3. Consumption of cloud services
Many applications use different services. For instance, an application that provides data exchange between delegations can use object storage in Cloud as a reliable warehouse and to share data. Local application can be deployed here with certain amount of caching, but the cloud can be used as the main data store.

4 technical aspects to consider
There are several technical challenges when creating a hybrid cloud solution. One of the most important components is the connectivity between the two clouds and the second is the orchestration layer for deploying workloads in multiple clouds..
1. Secure network connectivity
Since workloads will run on premises and in the cloud, you must decide what type of network connectivity is required between the two environments. The first option is to configure VPN connectivity from the local network to the public cloud. Then, the same layer network 2 in the public cloud it scales and can be accessed from your own local network. Most public cloud providers offer options for hardware- or software-based VPN gateways.
The second option is to have only Layer connectivity 3 for virtual machines in a public cloud with public IP addresses. This is more restrictive, since all virtual machines that need connectivity from your company will need to have public IP addresses. Public IPs are a rare commodity. They are quite expensive and also expose workloads to port scans for security vulnerabilities.
2. Low latency network connectivity
Most applications are sensitive to latency between various components and have WAN latency and “Be nervousWhen running an application in two clouds, can be very expensive from a performance and reliability standpoint. Nowadays, many data center providers establish high-bandwidth, low-latency links between their on-premises facilities and the public cloud.
3. High-bandwidth connectivity
Migration across a WAN can be time consuming and prohibitive. What's more, upload bandwidth, In most cases, it is much more expensive than download bandwidth. There are services like MegaPort that provide rental-based high-bandwidth connectivity between private data centers and public clouds.. This is a great model for customers who want a cross-cloud migration.. The option of renting space in a data center that provides such functionality should be sought.
4. Provisioning and migration functionality
Ideally, want a unique way to deploy applications on more than one platform. Try to choose two platforms that support the same language to describe the application. Another alternative is to use a cloud management platform that provides a high-level abstraction for application deployment and translates it to the underlying cloud platforms..
Cloud computing will continue to grow and, with her, the need for multi-cloud environments integrated with local systems. Therefore, hybrid cloud is a reality for business in this age of data 4.0 where the availability and integration of data is the key to its sustainability.
