How do you manage multi-cloud environments?
Productive and effective management of multi-cloud environments consists of:
- Automation: Utilizing automation and machine learning (ML) empowers IT teams to efficiently administer security, implement proactive solutions, and scale operations in multi-cloud environments.
- Compatibility: Due to data living across a variety of environments, the most effective management occurs when all of the containers are compatible. They must have the ability to be managed through a single interface for high-level, effective management to occur.
How do you move workloads across a multi-cloud environment?
The most efficient way to move a workload is via storage containers. Kubernetes and other types of container orchestration systems house single apps and all necessary software for the application to run. When data is stored in containers, workloads can be moved across cloud environments strategically and efficiently.
Duplication is also critical when you are transferring a workload to a new environment. It prevents any data loss or slowed performance in the new environment. Often, you do not know how your data will perform in different environments – ensuring data security through duplication is critical. If there is a secondary version that lives across the cloud, you will be able to default until you establish secure function within the new location.
The objective of distributing workloads across multi-cloud environments strategically is to promote the efficiency of apps and the viability of workloads. Moving workloads in containers to different clouds can be a complex process. Strategic placement is essential for the success of your applications and workloads, and can only be accomplished through effective cloud management systems.
What are the challenges of multi-cloud management?
There are a variety of challenges within multi-cloud management systems, each stemming from the complexities of large amounts of data living in a variety of platforms.
With so many workloads simultaneously needing attention, support, and deployment, structured management systems are critical. There is complexity within such a broad expanse of data within multi-cloud environments. Especially since applications have different dependencies and requirements. Multi-cloud management is complex from top to bottom, and requires structure and intentional design to be accurately utilized. If there is inability to see and manage data across clouds, there will be inability to pinpoint performance issues within the cloud, leading to risk of data loss and decreased performance.
Another issue with multi-cloud management is risk of data loss and cost of recovery. Most providers offer insufficient service-level agreements that do not provide the coverage of data services that enterprise organizations need. With different cloud environments making it difficult to move data, there are the additional challenges of unpredictable costs and usage spikes.
This is where uniform containers become absolutely essential. One of the largest challenges of multi-cloud management is balancing the movement and diversification of apps across environments with a variety of different formats without triggering integration concerns. Containers prevent these issues from occurring by hosting applications with uniformity, further enabling seamless portability despite varying types of public cloud environments.
