Introduction

Femas is an open source product form of Tencent Cloud's microservice platform TSF . It focuses on the running state of microservices and provides one-stop microservice management and control capabilities such as multi-frame unified service discovery, north-south and east-west traffic management, service observability, and configuration management. In the service architecture transformation, the core issues are difficult to reuse heterogeneous frameworks, difficult to manage and control surge traffic, and time-consuming for troubleshooting and recovery.

data plane: Femas uses the multi-runtime architecture design to standardize and modularize the underlying core capabilities of microservices, and assemble the basic components split in the microservice field through a reasonable architecture to meet diversified microservice scenarios. , lightweight, portable, low-cost, cloud-free vendor binding,Currently, the community provides governance data planes in two proxyLess modes: SDK and business-agnostic JVM TI Agent.

control plane: Femas provides a unified control plane standard protocol, a set of governance protocols, and multi-language and multi-data plane distribution.

ability

Registry manage: Femas implements the management of open source registries (currently supports Consul, nacos, eureka), including cluster management and service management. Users can configure the registry cluster on the Paas platform to view the cluster status and service list.
Service governance: Authentication, API management, Fuse downgrade, Access current limit, Service registration discovery, Service routing, Service event.
Service configuration: application configuration management, configuration hot update, Femas implements a set of standard configuration API interface, configuration is divided into governance rules,application configuration, open source side supports directly issuing governance rules through Paas platform , do not rely on other third-party components.
Service registration discovery: Femas implements a set of standard registration discovery API interfaces, and users can directly use the SDK provided by Femas to register and discover to mainstream open source registry centers.
Service monitoring:
- Metrics: Femas implements a set of standard API interfaces for business metrics. Femas uses micrometer to implement business metrics statistics by default.
- Tracing: Femas implements a set of standard tracing API interfaces. The SDK side is responsible for formulating OpenTracing log specifications and link collection. By default, Opentelemtry is used to collect Tracing

Feature

Provide SDKs for Java and Go to help users realize multi-language unified management on the same Paas platform.
Femas standardizes and encapsulates microservice capabilities and provides unified access to the Layer layer of irrelevant protocols, which facilitates the integration of a full set of capabilities into any protocol, and realizes the unified management of multi-protocol.
Femas abstracts the capabilities that a microservice application may need to use in the running process into standard API components, which are convenient for expansion and compatible with other open source component ecosystems.
The underlying capabilities of Femas are plug-in and standardization, and users can flexibly combine and match the microservice capability matrix according to their needs.
Femas is not bound to any specific components, as long as the components that conform to the Femas standardized protocol can be managed on the Femas platform, it is convenient for users at all levels to learn, use and develop secondary.
Sink-type non-intrusive access, zero cost for user transformation.

Java Agent bytecode injection

ServiceMesh service mesh(TODO)

Femas hopes to summarize Tencent's microservice product center's understanding of microservices into a platform to help users quickly build an enterprise-level microservice ecosystem.
Femas supports Tencent's internal ecosystem of billions of users.

Install the server

Runtime environment dependencies:

64 bit OS, support Linux/Unix/Mac/Windows, script startup supports Linux/Unix/Mac;

64 bit JDK 1.8+;

Maven 3.2.x+;

External database Mysql (optional)

Stand-alone deployment

mvn -Dmaven.test.skip=true clean install -U

cd femas-admin-starter/target/femas-admin-starter-$version/femas-admin/bin

sh startup.sh

The console configuration mainly includes:

Service port
Database configuration (no configuration required if using embedded database)
nacos address configuration (if you use configuration management, you need to configure)
skywalking web address configuration (requires configuration to obtain link information)
grafana address configuration (requires configuration to obtain metrics information)

Femas default Start with the embedded database:

The embedded database only supports single-machine deployment, and does not support cluster deployment. The embedded database data disk path is ${user.home}/rocksdb/femas/data/

To use the monitoring capability, the following configuration is required:

#Configure skywalking backend address
Femas:
  trace:
    backend:
      addr: http://skywalking WEB IP:PORT
#Configure Metrics grafana address
  metrics:
    grafana:
      addr: http://IP:PORT

Cluster deployment

Cluster deployment is the same as stand-alone deployment. The only difference is that the data source must be an external data source, so that the server side of Femas supports stateless horizontal expansion.

Configuration file configuration data source

spring:
  datasource:
    url: jdbc:mysql://IP:3306/adminDb?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useSSL=false&serverTimezone=Asia/Shanghai
    username: username
    password: password
    hikari:
      driver-class-name: com.mysql.cj.jdbc.Driver

The start command is

sh startup.sh external

Visit http://localhost:8080/index to see the console page

Login user name: admin, password: 123456, the user name and password are hard-coded, and the open source side does not impose any permission restrictions.

Preparation before the service is connected to the paas platform

step 1. Configure the registry(Before this, you must have a deployed registry cluster, Femas is not bound to any registry, you can host any registry to the Femas platform)

Cluster addresses support IP:prot comma-separated, or domain name mode

step 2. Create namespace

Registry for namespace binding configuration

The service list of the femas governance center is logically isolated in the namespace dimension. The service list is pulled from the third-party registration center. The pull condition is to access FemasSDK and the name of the service tag (namespace ID written by -D below) The space is the same as the namespace selected in the list.

After completing the above two steps, you can then access femas through the SDK to manage the service to the paas platform.

Springcloud access

Sample

Execute the script under the femas parent pom:

mvn -Dmaven.test.skip=true clean install -U

Add dependency

<!-- Native dependency of registry -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-consul-discovery</artifactId>
    <version>2.1.2.RELEASE</version>
</dependency>
 
<!-- femas middleware dependency -->
<dependency>
    <groupId>com.tencent.tsf</groupId>
    <artifactId>femas-extension-springcloud-greenwich-starter</artifactId>
    <version>${femas.latest.version}</version>
</dependency>

Currently Femas supports starter list directory: cd femas-starters/

The default supported version components are:

springcloud greenwich
springcloud 2020
springcloud gateway
springcloud zuul

Configuration file

Business application native configuration file, the path is: resources/bootstrap.yaml

server:
  port: 18001
spring:
  application:
    name:
      femas-springcloud-consumer
  cloud:
    consul:
      host: 127.0.0.1
      port: 8500
      discovery:
        serviceName: femas-springcloud-consumer
        instanceId: ${spring.application.name}-${server.port}-${spring.cloud.client.hostname}
        heartbeat:
          enabled: true
# nacos:
# discovery:
# server-addr: 127.0.0.1:8848

Femas component configuration file path: resources/femas.yaml (Ymal format, used to configure femas-related local configuration, such as paas address, custom registry cluster, custom governance rules, etc.)

# Configure the paas background address, if not configured, get the rules from the local configuration file
paas_server_address: http://127.0.0.1:8080
femas_namespace_id=Namespace ID
femas_prog_version=Service version

# Use the method provided by Femas to access the registration center, how to use dubbo or self-developed protocol
femas_registry_ip: 127.0.0.1 //Registry center cluster address
femas_registry_port: 8500 //Registry center port number
femas_registry_type: consul //registry type

#The following configuration is optional, which is used to configure and load the basic component type and local governance rules. If not, load the default configuration of femas.
rateLimit:
 type: femasRateLimit
authenticate:
 type: femasAuthenticate
serviceRouter:
 chain:
   - FemasDefaultRoute
loadbalancer:
 type: random
circuitBreaker:
 enable: true
 chain:
   -femasCircuitBreaker

Start service command

-javaagent:"{skywalking agent absolute path}/agent/skywalking-agent.jar"
-Dfemas_namespace_id=Namespace ID
-Dfemas_prog_version=Service version
-Dskywalking.agent.service_name=The name of the service registered on skywalking, which needs to be consistent with the name of the registration center
-Dskywalking.collector.backend_service=skywalking backend address, which can override the agent's conf configuration

Reference agent probe of skywalking

The service needs to specify its own namespace

Specify the group to which the service belongs, and cooperate with the realization of service governance on the SDK side

The service name registered to skywalking must be the same as the name registered to the registration center, otherwise the tracing link observation will not find the corresponding service.
