Advantages of CloudOps and Features of O&M on the Cloud

CloudOps is an extension of traditional IT operation and maintenance and DevOps. It realizes the re-evolution of operation and maintenance through cloud-native architecture, which fully helps enterprises reduce IT operation and maintenance costs, improve delivery speed and system flexibility and agility, enhance system reliability, and build a more secure and reliable Open business platform.

First. Advantages of CloudOps: The Dual Value of Cloud and DevOps

DevOps brings great convenience to application software development. Because cloud services have the characteristics of "software-defined everything" and elasticity and agility, they are very consistent with the concept of DevOps, and the advantages brought by the two are very similar.

Adopting the DevOps philosophy has the following four advantages and purposes:
1. Reduce overall costs
○ Reduce staff redundancy by coordinating different teams.
○ Reduce labor costs through continuous automation investments such as Infrastructure as Code (IaC), Ops as Code, etc.

2. Improve overall delivery speed
○ Greatly improve application delivery speed through agile form and automated construction.

3. Increase flexibility
○ Faster delivery means quick adjustments and increased efficiency.

4. Enhance the reliability of the system
○ Human error can be avoided through standardization, instrumentation, and automation.
○ Self-service management of the organization, reducing unnecessary miscommunication and MTTR (Meantime to Repair) for troubleshooting.

There are similar advantages to using cloud service management:

1. Reduce overall costs
○ Enterprises can reduce the personnel involved in hardware procurement and basic resource operation and maintenance, and do not need to consider the difference between various physical resources.
○ Cloud computing allows enterprises to consume resources on demand, and does not need to purchase a large number of fixed assets in advance for business peaks.
Create resources according to business changes.
○ Select the appropriate payment and resource type through the appropriate selection and resource application form.

2. Improve overall delivery speed
○ Through resiliency, enterprises can quickly respond to resource creation or release within minutes to hours
Processes that span days or even weeks.

3. Increase flexibility
○ Able to quickly adapt to market demands or extreme demands of various operational activities.

4. Enhance the reliability of the system
○ Cloud services naturally provide high-availability system design, such as multi-availability zones, backup and recovery, and hot migration, to reduce losses caused by physical resource failures.
○ The tools and service-oriented capabilities provided by cloud service providers can greatly reduce the cost of system construction. At the same time, through professional troubleshooting and diagnostic services, the difficulty of troubleshooting some problems and faults can be greatly reduced.
○ Ability to create more resilient, secure and standardized systems.

In summary, we can see that there are many similar advantages between Cloud and DevOps. The organic combination of Cloud and DevOps will bring greater value, including the above-mentioned cost reduction, delivery speed improvement, flexibility, and system improvement. reliability, etc.
Cloud and DevOps are natural, and DevOps combined with cloud computing not only improves efficiency and optimizes TCO, but it also enables our systems to work more reliably in an ever-changing complex environment. In recent years, we are pleased to see more and more enterprise and individual developers migrate their test and production environments to the cloud.

Second. Characteristics and challenges of cloud operation and maintenance

However, moving traditional DevOps directly to the cloud cannot make full use of the advantages of the cloud and obtain 1+1 equal to or greater than 2 benefits, because compared with the traditional DevOps operation and maintenance model, the automatic operation and maintenance model on the cloud and There are still some differences in thinking. This is also a challenge for some enterprises to establish a cloud-native automated operation and maintenance system after going to the cloud.

1. Differences in operation objects
○ In traditional operation and maintenance, physical computing, network, and storage hardware are directly operated.
○ For cloud operation and maintenance, most abstract resources are operated through software exposed interfaces or OpenAPI.

2. The difference between assets and resources
○ The traditional operation and maintenance mode operates on the assets of the enterprise, which needs to be fully squeezed to improve the utilization rate and utilization rate of a single machine.
Plan resources well in advance.
○ Cloud operation and maintenance is naturally elastic. In addition to improving the utilization rate of a single machine, it can also obtain resources and release resources on-demand.
Open API and make full use of OpenAPI and application grouping to manage and control resources.

3. Unify scale differences
○ The scale of traditional operation and maintenance operations is relatively small, and the management room is relatively clear and limited.
○ Cloud operation and maintenance can quickly and easily manage hundreds or even larger servers across multiple computer rooms through the elasticity of resources.

4. Security auditable
○ Many high-frequency operations in the cloud are automated tasks, and the operation sources and objects are relatively complex, and the timeliness requirements for operation auditing and operation sources and alarms are relatively high.
○ The services provided by the cloud can be directly exposed to the public network through a command, which requires more design and thinking about security and network planning capabilities to reduce system risks.
○ High-frequency programmable automatic operation and maintenance requires better auditing and problem tracking capabilities to avoid problems that are beyond authority and are not easily tracked.
