                                             GLOBAL  ACCELERATOR


Global accelerator(GA) is a network accelerator service, benefiting from the high-quality bandwidth and global transmission networks provided by Alibaba cloud.It enables nearby access to the internet and cross-region deployment applications, improving the user experience of internet service

  

                          


FEATURES:


 High Quality:

  •   Global network resources

  •   Massive TCP/UDP port Listening

  •   TCP protocol optimization


High Reliability:


  •   Global cross-region SLB

  •    Dual scheduling from DNS and IP


Monitoring and Maintenance:


  •    Support purchase and configuration wizard

  •     support to retain client source IP

  •     Support network quality deduction


High security:


  •     High defense,

  •    WAF configuration and  protection

  •    Anti-DDoS Security

  •     Access control



VISIBILITY AND MONITORING



  • Source IP address for end users are visible

  • Bytes in/bytes Out

  • Packets In/packets Out

  • L4 connections


FAULT TOLERANT DESIGN





  • Multiple servers in different zones on the front

  • Use of weight to decide ratio of the backend servers

  • Failover to another backend server in case of outage


COMPARISON OF WITH GLOBAL ACCELERATOR AND WITHOUT GLOBAL ACCELERATOR


Without  Alibaba cloud Global accelerator:



  • Customer traverse public Internet from ens-to-end to reach the application

  • Multiple hops add additional latency and packet loss


With Alibaba cloud Global accelerator



  • Customers access to the nearest alibaba cloud edge location

  • Optimized routing to reduce latency

  • Lower packet loss and jitter


MAIN CHALLENGES FACED BY CUSTOMERS DAILY :


  •  Bad internet quality impacting country to country transmission

  •  Service availability is lower than expected for internet based services

  •  IP configuration and management become increasingly complicated


When user access websites across borders,the following issues may occur:


cross-border Network Quality:

              The application performance may be reduced due to high latency, network congestion and packet loss.

The Last-mile Problem:

        The network performance of the last mile depends on the local Internet service provider(ISP)

Optimization challenges : 

         MPLS and WAN optimization technologies cannot be used to accelerate internet applications

Architecture issues :  

                  Multi region application deployments bring operational and maintenance challenges


Solution:

SCENARIO : WEBSITE ACCELERATION OUTSIDE MAINLAND CHINA


USER PROFILE:


  •  Overseas servers

  •  Mainland china customers

  •  Domains with ICP


CHALLENGES :


  • Poor cross-border network connection

  • Higher costs to build a new server

  • Difficult to servers across multiple regions



INTEGRATION AND SECURITY:


  • WAF and Anti-DDoS supported

  • CDN back-to-region Integration

  • Multiple region access over BGP

  • DNS and GTM integration


ACCELERATION :


  • Global traffic distribution

  • Licensed cross-border connections

  • Support servers in third party IDCs and Cloud providers

  • High availability SLA


CASE STUDY:


      A german cross-border e-commerce company that sells maternal and child supplies.It has large number of consumers in china


BEFORE ACCELERATION



CHALLENGES 


  • user experience is poor due to cross-border CDN

  • Architecture cannot be modified by china team


AFTER ACCELERATION


 



ACCELERATION:


  • CDN back-to-origin acceleration

  • Multiple region across over BGP


BENEFITS:


  • Network performance is improved by  more than 10 times

  • 10 minutes for deployment

  • No system modification



MARKET ANALYSIS


CHINESE COMPANIES GOING GLOBAL: 


     More and more chinese companies are seeking to expand their internet-facing services to the international market,especially in the Gaming, Web application,Mobile phone and E-commerce.


FOREIGN COMPANIES ENTERING CHINA:


     The number of foreign companies entering china is increasing rapidly.This number reached 0.58 million in 2018.these foregin companies call for the internet services to provide better services for mainland China
