What is the Difference Between CDN and GDN?

What is CDN?

A CDN can be termed as a network of servers distributed geographically to deliver static content to the user allowing the website to cache the content quickly due to being closer to the user. The CDNs are linked between origin servers and edge networks to cache the static content through and let the origin server deliver the dynamic data and attain a quick response from the website and to the user over the edge. 

What is GDN?

The Global Data Network or GDN offers dynamic content incorporated over the edge which the CDN does not offer and can be further described as a combination of a streaming data processing engine and NoSQL databases with minimal latency across the globe.

What is the difference Between CDN & GDN?

Content Delivery Network (CDN) and Global Data Network (GDN) both serve as data replication centers across the globe to maintain a faster, secure, and scalable data transmission to the end-user. However, both have their drawbacks and benefits regarding data as well as content types over the internet.

In today’s times, websites, APIs, and applications need to possess a low latency rate and be highly responsive to the users. This can be achieved through the deployment of data centers carrying associated data over the edge and close to the user.

CDNs are intended to deliver static content, allowing cached data from the origin to multiple PoPs. But they do not aid in providing dynamic content type at the edge, as the transition of dynamic content would acquire many complexities in order to be delivered across the globe. Dynamic application data requires a single backend datacenter to work efficiently and it has proved very challenging to cope with latency and consistency problems, as well as distributed databases and dynamic content for a distributed application over the edge network.

The GDN, however, is Macrometa’s solution to such complications providing regular data types as well as query layers(c8ql) utilizing the Conflict-Free Data Type Technology through which data types can be replicated across globally distributed network replicating data where it is requested. Moreover, GDN provides cutting-edge technologies for distributed and multi-model databases coupled with the c8ql query layer. 

Why Macrometa?

Macrometa’s GDN architecture is based on a geographically distributed CRDT and materialized view engine for data replication destined to ensure consistent data distribution across 175 points of presence and hundreds of edge locations. This enables the developers to experience less latency and indulging performance for the development of a website, IoT applications, APIs, and cached data around the globe.

Closing thoughts

Content Delivery Network or CDN is still being utilized in the development sector, as it is known for its security, redundancy, and lesser load times, but GDN has provided superior services facilitating developers as well as web users due to its instant performance and consistency guarantees anywhere in the world. Macrometa delivers quality services in relation to the dynamic distribution of data types including database reads, writes, and queries with less than 50ms round trip latency rate due to its presence at the edge.
