personnel to the ITIL training at the manager level is very important.4. Set up realistic return expectations and set benchmarks for monitoring and improvement.Any internal change in an enterprise takes time to accept, and so does the implementation of itil. In the implementation of ITIL, it should focus on improving customer services. With the maturity of the process, the return on investment will be gradually recognized.To determine the final result, it should focus on the strategy and commun

: Data Services can be consumed through reliable (such as JMS on MQ series) or unreliable (such as HTTP) message transmission protocols. Some data services may only be provided by certain transmission tools based on this function.Message exchange mode: Data services can be accessed through four main message exchange modes: Request-response (strict SLA), request-response (loose SLA), I .e., release, release,

clouds. For example, if your service spans private data centers and AWS, amazon's AWS CloudWatch is hard to achieve this. This requires us to establish a monitoring system across different regions and run it in a dynamic native container environment.Monitoring APIIn a microservice environment, APIs are generic. Essentially, they are the only component that exposes services to other teams. In fact, the API response and consistency can be viewed as an "Internal

uncontrollable for developers, therefore, we hope that users can select their own data centers when creating applications. SLA. If the App Engine can set some SLA terms like S3, users can deploy applications on the App Engine with greater confidence. New languages: such as PHP. However, if you add a new language to the existing App Engine architecture, the workload will be very high, because nearly half

an open and standard way of service, so that service consumers can conveniently find the services, to promote service reuse and management. Many ESB products do not include functions such as service registration, storage, publishing, and subscription. These functions include the UDDI library. Therefore, an ESB generally requires a Service Registration/Repository to collaborate with it. The ESB executes various arbitration logic, and the registration database provides the necessary metadata info

Specifies that a deactivated version (for example v=3.0 ) will always return the current frozen version. The Maps API for business SLA does not apply to the current experimental version. The Maps API for business app must use the current release version (currently 3.9) or an earlier version in order to apply

developer is the person who is responsible for the controller or model layer in the Model-view-controller (MODEL-VIEW-CONTROLLER,MVC) architecture. In an SOA environment, these developers are now responsible for the service implementation. They do not need to know when, how or why to invoke the service, and who invokes the service. What they are concerned about is what the service does and what service level agreements it needs to meet (AGREEMENT,SLA

outside your control, and the benefits are diminishing. For example, the percentile is frequently used in service level objectives (SLO) and service level agreements (SLAs), which are contracts that define target performance and service capabilities. An SLA may specify that the service is considered to have a median response time of less than 200ms and that the No. 9900 decimal point is within 1s (if the response time is longer, it should be reduced)

Now that MVC is maturing, it's confusing to face different versions of MVC--what's the difference between them? Below I gather the information I collected, so that we can better understand the different versions of MVC features, but also easy to check.View Engine:View Engine is responsible-rendering of the HTML code from your views to the browser.MVC 2 UsesOnly Web Forms view engine (. aspx) as a default view engine.MVC3 uses Razor view engine (. cshtml for C # and. vbhtml for Visual Basic) and

The data stream service, also known as NetFlow, is a network protocol that collects IP traffic information as records and sends them to the Collector for traffic analysis, it is a new technology that is being gradually improved. NetFlow provides network capacity planning, trend analysis, and data priority information for service providers and enterprises. This technology can also be used for IP-based billing applications and SLA validation services. I
