Nexus
A centralized platform for managing and organizing data, such as a data management system that allows organizations to store, analyze, and share data across multiple departments or locations.
Docker
Docker is an open-source platform that allows developers to easily create, deploy, and run applications in containers. Containers are lightweight, portable and self-sufficient execution environments that package an application and its dependencies together and run them consistently across different environments. With Docker, developers can create, ship, and run applications in isolated environment, eliminating the “works on my machine” problem. Docker also provides a centralized hub for storing and sharing container images called Docker Hub and support for orchestration, enabling the management of multiple containers running on different hosts, allowing for scaling and managing applications in production environments. It is widely adopted in the industry, supporting multiple platforms and integration with a wide range of tools.
Docker Swarm
Docker Swarm is a native orchestration solution by Docker that allows management of multiple Docker hosts as a single virtual host. It makes it easy to create, deploy and scale services in a Dockerized environment. It provides built-in load balancing and service discovery and allows IT administrators to deploy, manage and scale their applications in the swarm cluster. It also provides “Stacks” feature to deploy multi-services applications using a single command. It is built on top of the Docker Engine and fully compatible with the standard Docker API, it can be controlled by any tool that can communicate with the Docker daemon.
Kubernetes
Kubernetes (K8s) is an open-source container orchestration system for automating the deployment, scaling, and management of containerized applications. It was developed by Google and is now maintained by the Cloud Native Computing Foundation (CNCF). It provides automated rollouts, self-healing, automatic scaling, service discovery and load balancing, namespaces, configmaps, secrets. It is considered the de facto standard for container orchestration, widely adopted in the industry and supported by major cloud providers. It can be run on-premises or in a hybrid environment and integrates with a wide range of tools.
Terraform
Terraform is an open-source infrastructure as code software tool that allows users to define and provision infrastructure using HashiCorp Configuration Language (HCL). It provides an execution plan that describes the changes that will be made and allows previewing before implementation. It allows management and versioning of infrastructure as code, enables management of multiple environments, and provides resource provisioning, modularity, state management, and plugins support. It can integrate with a wide range of tools and services.
CloudFormation
AWS CloudFormation is a service that allows users to use templates to provision and manage infrastructure resources on AWS. It enables the creation, update and deletion of a collection of resources as a single stack, automates the process of creating and configuring resources, has versioning, dependency management, reusability and drift detection capabilities. It uses templates written in JSON or YAML to describe the desired state of the infrastructure and allows management via AWS Management Console, AWS CloudFormation command line interface (CLI), or the CloudFormation API.
Ansible & Puppet
Ansible and Puppet are open-source IT automation tools that help users automate repetitive tasks related to configuration management, application deployment, and provisioning. Both use a simple, human-readable language to describe automation tasks and provide features such as idempotency, modularity, inventory management, and the execution of ad-hoc commands. However, Ansible uses a push-based architecture, doesn’t require agents on the managed nodes, while Puppet uses a pull-based architecture, and requires agents on the managed nodes. Both are widely used in the industry and have their own set of pros and cons, it depends on the use case and the organization’s specific requirements which one to choose.
10 AWS Services
Amazon Web Services (AWS) offers a wide variety of services that can be used to build and run applications in the cloud. Some of the key services include:
Amazon Elastic Compute Cloud (EC2) for resizable compute capacity, Amazon Simple Storage Service (S3) for object storage, Amazon Virtual Private Cloud (VPC) for creating private, isolated network, Amazon Relational Database Service (RDS) for launching and managing relational databases, Amazon Elastic Block Store (EBS) for persistent block-level storage, Amazon Elastic File System (EFS) for shared file storage, Amazon Elastic Load Balancer (ELB) for automatically distributing incoming traffic, Amazon Simple Notification Service (SNS) for sending and receiving messages. These are some of the popular services and AWS offers many more services for different use cases such as security, analytics, application integration and many more.
ELK
ELK is an acronym for Elasticsearch, Logstash, and Kibana, a set of open-source software tools used for log management and analytics. Elasticsearch is a search and analytics engine, Logstash is a data collection and processing pipeline, and Kibana is a data visualization tool. Together, they can be used to collect, store, and analyze log data from various sources, such as servers, applications, and network devices, to troubleshoot issues, identify performance bottlenecks, and detect security threats. ELK is commonly used in DevOps, IT operations, security and compliance.
Grafana
Grafana is an open-source analytics and monitoring platform that allows users to visualize and analyze time-series data from various data sources, including Prometheus, InfluxDB, Graphite, Elasticsearch, etc. It provides a wide range of visualization options and features such as data source plugins, alerting, annotation, templates and plugins. It is used in various industries such as IT operations, network monitoring, application performance monitoring and IoT. It allows creating custom and interactive dashboards and helps to detect and respond to critical events.
New Relic
New Relic is a software analytics company that provides a cloud-based platform for monitoring and analyzing the performance of web and mobile applications. It provides a wide range of tools and features such as Application performance management (APM), Real-user monitoring (RUM), Server monitoring, Synthetic monitoring, Mobile monitoring, Alerting and Dashboards and reporting. These features allow users to monitor and troubleshoot the performance of their applications, identify and diagnose issues related to application code, infrastructure, and third-party services, and detect and respond to critical events. It is widely used in various industries and by development teams to monitor and troubleshoot the performance of their applications in real-time.
Nagios
Nagios is an open-source IT infrastructure monitoring tool that allows users to monitor the availability and performance of IT resources such as servers, applications and network devices. It provides features such as host and service monitoring, event correlation, notifications, reporting, plugins and web interface. It is used to detect issues and generate alerts, allowing users to take prompt action to resolve them. It is widely used across various industries by IT operations and network operations teams to monitor the availability and performance of their IT infrastructure.
Prometheus
Prometheus is an open-source monitoring system and time series database that is widely used in cloud-native environments and infrastructure monitoring. It is known for its scalability, reliability and pull-based data collection model, allows collecting metrics from different services and systems in a unified way, and provide a powerful query language to analyze and visualize data. It is integrated with other tools such as Grafana for visualization, Alertmanager for alerting and various exporters for collecting metrics. It has a large and active community of users and contributors.
