Anycast Cloud

The LACTLD Anycast Cloud is a collaborative network that seeks to strengthen the DNS infrastructure and stability in Latin America and the Caribbean. Since its formalization at IGF 2016 in Guadalajara, the Cloud has been growing with the incorporation of new clients and nodes. Thus, it has contributed to the Internet strengthening and development in the region.

What is Anycast?

Anycast is an addressing technology that allows optimal and efficient use of networks. In an Anycast Cloud, a series of nodes (servers) store copies of the same “database”, which is made up of the different Cloud clients zones (list of managed domains, for example, .sv, .do, .gt). In turn, these nodes, located in dispersed geographical locations, share and respond to the same IP address. Then, when this “database” receives a query, the routing systems first decide which of all the available nodes is the closest one to the query origination point and, then, direct the information to this geographic endpoint of the Cloud, thus speeding up the answers.

For example: If our network has nodes available in Santiago de Chile, São Paulo and San José de Costa Rica, and it receives a query from Santo Domingo, the routing systems first determine that the Costa Rican node is the closest one to the query origination point and, then, route the traffic there.

Which are its main benefits?

Optimal load management

Due to its distributed nature, the network dynamically activates the answers to the users queries according to the availability of each of the nodes. Furthermore, it grants geographic and topological diversity, and promotes local traffic exchanges.

Shorter response times

By efficiently managing queries, the Anycast Cloud can significantly reduce response times. Consequently, clients gain greater availability to respond to the users queries, and nodes also acquire operational speed and greater independence from the external network to provide their service.

Robustness and resilience

If one of the nodes goes down or stops working due to some inconvenience, it will automatically be removed from the available routing options, and future traffic will continue to be directed to the remaining nodes of the Cloud. Thanks to this mechanism, clients —who store copies of their zone in all the nodes of the network— have instant recovery instances in the case of a downfall or attack.

Efficient use of infrastructure

The LACTLD’s Anycast Cloud allows an efficient use of participants infrastructure.

LACTLD’s Anycast Cloud

LACTLD’s Anycast Cloud distinguishes itself by being:

Regional
Collaborative
Non profit

Furthermore, LACTLD’s Anycast Cloud is based upon best effort principles, and it does not seek to compete with existing commercial providers.

LACTLD (Latin American and Caribbean ccTLDs Association) has pioneered the development of a Anycast Cloud of this kind.

This initiative has strengthened the infrastructure and stability of the Cloud’s clients and nodes as well as the entire regional network in terms of resilience, robustness, traffic load management, speed and availability.

Nodes and Clients Testimonials

.SV (El Salvador)

Sergio ‘Lito’ Ibarra, President and CEO
 
The LACTLD Anycast Cloud has only advantages. The fact of being part of this project, gives us the guarantee and security that what it will do is to grow more and then give us, without us even having to do anything, more security, more stability, more redundancy, and ultimately a better operation for our users. The conditions are excellent

.CL (Chile)

Eduardo Mercader Orta, Director of Operations and Systems
 
“At NIC Chile, we believe that the LACTLD’s Anycast Cloud has represented a great opportunity to help strengthen the DNS infrastructure and the collaboration among the region’s ccTLDs”.

.GT (Guatemala)

Luis R. Furlán, Director of .GT Domain Registry
 
 “The LACTLD’s Anycast Cloud is a collaborative project that allow us to join as a region making shared efforts and strengthening the DNS service in Latin America and the Caribbean. By participating as network clients, we increase the availability of NS records reinforcing the resilience of our ccTLD”.

.DO (Dominican Republic)

Alexandre Pérez, Infrastructure Coordinator 
 
“The participation of NIC .DO as a client of the LACTLD’s Anycast Cloud has allowed us to improve our response times in the region. Also, the LACTLD’s Anycast Cloud has become a key piece of our resilience strategy due to its stability. We understand that this collaborative effort has been very fruitful and will continue to improve as it grows”.

.PR (Puerto Rico)

Pablo Rodríguez, Executive Vice President

“Our region lacked this type of service and LACTLD fulfilled a very important objective and mission for all TLD operators to offer one that is built on a system that is resilient, robust, secure, because that is precisely the essence of the Internet”.

.TT (Trinidad & Tobago)

Patrick Hosein, CEO
 
“The main benefits we have achieved so far is faster response times and a more robust service. Besides, this initiative will definitely improve resilience because we now have instances within the region itself and we no longer need to depend on instances outside of the region. And in terms of security, we have better control”.

.MX (Mexico)

Ernesto Bojórquez, Chief Executive Officer

“It has very important benefits, which are difficult to build autonomously and individually. I consider that collaboration brings additional synergies to the benefits of the project itself. It simply allows you to have a greater capacity for your services, and the truth is that it does not really have an important cost. On the contrary, the cost that you could pay, in reality, becomes a contribution that you make to the community and to the entire Internet in the region”.

.BR (Brasil)

Marcelo Gardini, Information System Manager
 
“It is the best option to serve well all DNS clients. Those who operate ccTLDs, those who operate DNS know the importance of having a distributed network. The more distributed the DNS service is around the region and around the world, the more secure it is going to be in relation to failures, attacks and any problem like that. We have to strengthen the Internet community. The Internet works on the basis of cooperation”

Blacknight

Michele Neylon, Founder & Chief Executive Officer 
 
“You are getting all the benefits with practically none of the downsides. I mean you are able to build up the resilience of your ccTLD and, thus, improve that experience for users without bankrupting yourself and I think that is really important. So, that helps to build up the overall resilience of the DNS both in the region and for the region”.

.GP (Guadalupe)

John Broomfield, Chief Technology Officer


“The impact it has had is precisely what we were looking for. It has given us and the region stability, redundancy and latency time drops in access. It works as requested. Not participating is missing a very good opportunity that has been provided”.

.PY (Paraguay)

María José Franco Lugo, IT Consultant  
 
“It promotes local exchange. It reduces response times and, in this way, the nodes become more agile in their operation, strengthening their robustness. One way to position the region in the world would be to collaborate with the stability and resilience of the Internet”.

.GY (Guyana)

Rayman Khan,
.GY Administrator
 
It is a very much needed service provided to strengthen the DNS infrastructure of ccTLD registries in the LAC region. One of the great benefits of joining the project is that we put more redundancy in the system, faster response times for DNS queries. So the customer will be more satisfied and we will have a more reliable, more robust system. But one of the main benefits we received is the excellent support from the LACTLD community, especially at the time of installation”.
