These days, many enterprises use multiple public cloud and private clouds as a part of their cloud deployment. According to the cloud report 84% of enterprises have a multi-cloud strategy and majority(54%) use both public clouds and private clouds as a part of multi cloud strategy. Also, enterprises now say that they run a majority of their workloads in the cloud. Company’s reliance on them is also increasing. Due to these increases, optimizing cloud spending is their first priority and governing their cloud usage is a close second. So here multi-cloud management tools come in. These tools allow organizations to centralize their monitoring of cloud spending and usage, apply governance policies, secure access and enable self-service. Some include cloud migration and/or backup and disaster recovery features.
Many leading CMPs are available from small vendors that completely focus on multi-cloud management, but larger technology companies are acquiring many small vendors. If you’re new to the world of multi-cloud management, then you must know its details before adopting it. Here we’ll see multi-cloud management tools, best practices and challenges. Before proceeding, let us see what multi-cloud management is.
What Is Multi-Cloud Management?
When an organization uses more than one cloud platform service for its different application needs. Multi-cloud is comprised of a private, public cloud to fulfil the organization’s end goals that vary organization to organization. Multi-cloud management uses different architectures, like Infrastructure-as-a-Service (IaaS), platform as a service (PaaS) and Software-as-s-Service (SaaS), to achieve a business goal. According to the requirements of specific workload/applications, different cloud providers are used. Multi-cloud is a strategy applied by CXOs, technology architects. It allows enterprises to select different cloud services or features from various providers. This will allow companies to select public, private or hybrid cloud options and consolidate multi-cloud to make customized plan.
How Does Multi-Cloud Management Works?
Cloud Native functions are architected such as to run in the elastics and distributed nature of modern cloud computing platforms like AWS, private cloud like OpenStack. Multi-cloud strategies include use of hybrid environment, but it relies on more than one public cloud provider such as AWS, GCP, Azure. The approach eliminates the requirement for complete cloud migration since some sensitive data remains on that enterprise’s on-premise service.
Enterprises generally choose to store some user data on-premises, by use of one cloud provider for its IaaS requirements and another for PaaS or SaaS requirements. Various cloud service providers are used for various unique business functions.
Challenges In Multi-Cloud Management-
1. Performance-
It is a task to run periodic speed and performance checks on your web or mobile app, particularly in complex multi-cloud environments. It can be taxing for your developers team to monitor data and identify problems single-handedly.
2. Costs-
Unwanted expenses rises due to poor multi-cloud management. Sometimes, if you’ve integrated multiple cloud services in your application, it might be a possibility that you may not use all the benefits to their full capacity. And in such a way, you end up paying for services that are not even accessed.
3. Delays With Manual Processing-
Workload management that span over multiple and diverse platforms creates a need to address real-time processing and orchestration. It plays a vital role in getting the apps into productions and ensures their continuous performance. But, manually processing of all these actions can cause delays in delivering timely results.
4. Cloud Sprawl-
Cloud sprawl occurs when users fail to decommission non-utilized cloud computing instances or services- main reason being the workloads that frequently move between clouds. This makes it challenging to get resource visibility and affects the cloud bill.
5. Migration-
Most of the organizations faces challenges while migrating to multi-cloud especially when it comes to multiple data centers, remote locations and mobile uses. Checking of secure access to cloud assets with legacy networks often leads to two options — backhauling cloud traffic to a central internet access point or sending cloud traffic directly onto the Internet. Allowing organizations to migrate applications with their pre-existing standards and policies across the new cloud network, efficient cloud management is necessary.
6. Data Security-
Like data centers, multi-cloud environments also requires a robust security framework. There is a continuous data exchange between multiple clouds, so it is important to secure sensitive data with many layers. If an attacker has to penetrate more levels, the better chances are that the attacks will not be successful.
