Incident & Problem Management

Act as incident manager for P1/P2 issuesCoordinate resolution and communicationsPerform root cause analysis and recommend permanent fixesEscalate unresolved issues that required software coding to Level 3 or engineering teams

Change Management

Perform operational impact assessmentPart of the CAB to review and approve changePre-Change Preparation such as review Change Request and Release PlanSupervise post-change production verificationDocumentation update and knowledge transferPost change review and feedback

Patch Management

Perform patch management readinessStakeholder coordination and team coordinationSystem Readiness and Post-Patch ValidationDocumentation update and knowledge transferCompliance and audit readiness

Documentation and Compliance

Operational documentation. SOPs, Incident response checklist, RCA, PIR, monitoring and alert guidebookConfiguration & Infrastructure Documentation. System configuration baseline, application dependency maps, environment inventories such as hosts, services, accountsKnowledge Base Articles for level 2 enablement and faster resolution e.g. Known Errors and Fixes, Frequent How-To Guides, Script Repositories, Lessons LearnedKnowledge Management

Configuration Management

Perform validation and accuracy of configurationsMaintain readiness of operational documentationPerform audit to confirm compliance of configurationsCMDB asset verificationChange-linked configuration trackingEnsure environment consistency between DEV – IVVQ – ISO-PROD – UAT and PROD

Testing and Verification

Ensure operational readiness testing before production deployment rolloutEnsure post-change verification coordinationPerform regression and sanity test following patching or upgrades, in UAT and PRODParticipation in user acceptance testing

Knowledge Management

Documentation of resolutionKnowledge Base ContributionValidation of knowledgeSubject Matter Expertise Sharing

Root Cause Analysis

Gather logs, system metrics at the time of failureReproduction of issues in a controlled environment to understand the conditions under which it occursDetermine the scope and severity in terms of the systems affected, downtime duration and business impactNarrow down the possible sources of causing the failureUse of diagnostic tools such to analyse the application behaviourCorrelation of events to sequence the chain of events leading up to the failure and identify the dependencies

KAST (Kubernetes Analytics Stack)

THALES proprietary Kubernetes-based platform that provides a foundational digital infrastructure across Thales business domain

Kubernetes

Kubernetes is an open-source platform developed by Google for automating the deployment, scaling, and management of containerized applications (typically Docker containers).

Docker

Docker Compose is a tool for defining and running multi-container Docker applications using a single configuration file (docker-compose.yml). It allows you to define, manage, and run multiple interconnected Docker containers as a single service stack.

Kafka

Apache Kafka is a high-performance distributed streaming platform used for building real-time data pipelines, stream processing, and event-driven architectures.

EMQX

EMQX is an MQTT broker that acts as a message middleware between publishers (e.g., sensors, devices) and subscribers (e.g., apps, dashboards, databases) using the MQTT protocol, which is a lightweight publish-subscribe messaging protocol ideal for low-bandwidth, high-latency, or constrained devices.

Elasticsearch

Elasticsearch is a distributed, open-source search and analytics engine built on top of Apache Lucene. It is widely used for full-text search, log and event data analysis, and real-time data exploration.

MinIO

MinIO is a high-performance, distributed object storage system that stores data as objects (like files, images, videos, backups) in buckets

Zookeeper

Apache ZooKeeper is an open-source coordination service for distributed applications. It provides a highly reliable, consistent, and available mechanism to store metadata, configuration, and state information. It complements Apache Kafka by acting as a metadata management and coordination layer in Kafka’s traditional architecture. ZooKeeper ensures reliability, consistency, and fault-tolerance in Kafka’s distributed setup.

Sparks

Apache Spark is an open-source, distributed computing system designed for fast, large-scale data processing. It was built for performance, especially for iterative algorithms in data science and machine learning.

RHEL

RHEL is a certified Linux operating system optimized for reliability, scalability, and security in business and production environments.

Ansible

Ansible is an open-source IT automation tool developed by Red Hat that simplifies the management of servers, applications, and infrastructure. It allows DevOps and system administrators to automate tasks such as configuration management, software deployment, and orchestration. It uses simple, human-readable YAML files (called playbooks) and SSH

Prometheus

Open-source monitoring and alerting toolkit that is used to collect, store and query metrics, for the monitoring of infrastructure, services, containers and microservices

Grafana

Open-source analytics and visualization platform used for monitoring, observability, and alerting. Commonly used with Prometheus
