Providing support and maintenance 7/7 24/24 open source clusters of ELK (Elasticsearch, Logstash, Kibana) as well as training.

Acquisition of additional modules at the ELK community layer, the expected modules are at least the following ones:

- security,

- centralized monitoring,

- alerting module,

- machine learning module.

Acquisition of elastic search clusters administration modules of ELK community layer.

The support will be:

- support with commitments in working hours 5 days / 7 (call standard),

- support with commitments 24/24 and 7 days / 7 (advanced call).

EDF will offer services of the open source solution ELK to all EDF management. These subscribe to a service offering allowing them to use the ELK stack for their applications. The infrastructure that carries this service is internalized in EDF data centers.

The ELK stack is also deployed and used directly by EDF applications outside the internal service offer, as well as by other entities of the EDF group (such as Enedis).

Each server, and therefore each "node of an ElasticSearch cluster" must be able to be associated with a notion of "availability zone" to guarantee high availability within a cluster of several nodes distributed in several available zones.

The quantity is thus expressed in "nodes", 1 node is 1 server of "cluster", 1 cluster is 1 set of server.

For the total duration of the contract, the number of nodes could be from 1,650 to 6,600 spread over about one hundred clusters.
