Scalability (extensibility) is a design indicator of the computational processing power of software systems, high scalability represents a kind of elasticity, in the expansion of the system growth process, the software can guarantee exuberant vitality, through very few changes or even just the acquisition of hardware equipment, can achieve the entire system processing capacity of linear growth, Achieve high

when some application logs produce problems after an asynchronous response triggers a lambda call. Or custom practice occurs after a synchronous triggering of a lambda call Scalability and utilization of the infrastructure Types of resources Scalability Utilization Enterprise-owned IDC Week level Low Amazon EC2 Minute level

. Availability (availability) Usability is the probability or time share expectation that the system can run normally during a certain time of inspection. The study time is a specified moment, then it is called instantaneous usability; the time of the visit is the specified period, and the period availability is called. It is a measure of the equipment in use after the actual use of efficiency, is the equipment or system reliability, maintainability and maintenance of the integrated characteris

Modify tablespaces (modify the automatic scalability of data files) and Data scalabilityModify tablespaces (modify the automatic scalability of data files)When creating a tablespace, you can set the automatic scalability of the data file. When a new data file is added to the tablespaceYou can set Automatic scalability

Recently need to use Redis in C #, found on the Redis official website Servicestack.redis, finally in the test found that this is a pit, 4.0 has been charged, the latter had to find the final version of the 3 series, the final test found that there is still a bug or I will not use. There is no way, it is best to find the Stackexchange.redis, support asynchronous client, it is said that performance is better than Servicestack.redis, and it is said that the stack overflow is also used by this clie

Detailed description of javascript Object scalability, and javascript scalability Scalability in javascript objects refers to whether new attributes can be added to objects. All built-in and custom objects can be displayed as extensible objects. For host objects, it is determined by the javascript engine. The following functions are used to set object

the overall architecture is also easy to deploy because you only need to copy the deployment unit-a file or directory-to the machine running the corresponding kind of server. This is a good way for a relatively small application to work. However, for complex applications, the overall architecture becomes unwieldy. For developers, large, monolithic architecture applications can be difficult to understand and maintain. This is also an impediment to frequent deployments. To deploy a change to an

Many people talk about " microservices " and are grappling with an old problem more than 20 years ago ; Particle size "; What is the " granularity" of microservices partitioning ? More than 20 years , many people are taking a " Standard answer " ; particle size Span style= "font-family: ' Helvetica Neue '"; In doing software development. Unfortunately, when you have been using the so-called " Standard a

use different databases. Applications produce different kinds of data, and relational databases are not necessarily the best choice. In some scenarios, a NoSQL database might provide a more convenient data model, providing more performance and scalability. For example, an application that produces and queries strings takes a character search engine such as Elasticsearch. Similarly, an application that generates social image data can take a picture da

Similarly, an application that generates social image data can take a picture database, for example, neo4j; therefore,

The birth of MicroServices is not accidental, it is the product of the rapid development of the Internet, the rapid changes in technology and the traditional architecture can not adapt to fast changes, such as the impetus of the emergence of multiple factors.The birth of MicroServices is not accidental, it is the product of the rapid development of the Internet, the rapid changes in technology and the tradi

old and poorly maintained systems, which can take the "if the application cannot be broken, do not try to solve it" strategy, where the reuse of SOA assets should be a better solution. legacy applications cannot change the way data is stored: in this case, it is necessary to consider if the data is still in the chimney or centralized storage, that the application of microservices is business value, need to consider whether the segmentation of the dat

When you choose to build your application as a microservices, you need to determine how the application client interacts with the microservices. In a single application, there is only one set of endpoints. In the microservices architecture, each microservices exposes a set of endpoints that are usually fine-grained. In

Attention:If you are working on microservices, there is a need for mutual invocation between services, and the interfaces between services and APIs must generate the management documentation of the system. If you want to better manage your API, you want to have a tool to solve all the API-related things one-stop, then, swagger will be a good choice, the following for you to introduce swagger is the use of methods, if there is wrong, but also to correc

Micro-Service ArchitectureThe birth of MicroServices is not accidental, it is the product of the rapid development of the Internet, the rapid changes in technology and the traditional architecture can not adapt to fast changes, such as the impetus of the emergence of multiple factors. In the Internet era, the products usually have two kinds of characteristics: rapid demand changes and large user groups, in this case, how to build a flexible, easy-to-e
