Container management software helps automate the process of creating, deploying, scaling, and managing the availability of software containers. It optimizes how and where to run containers and also which systems to put them in. It automates load balancing, log management, and monitoring, along with other processes. A container is a lightweight package that puts together a single application and its dependencies, making it easier to develop, deploy, and manage apps across complex IT environments. It’s used for cloud-native, distributed applications and also to package legacy applications for enhanced portability and effective deployment.
Container technology is seen as an efficient and affordable way to manage resources, apps, and microservices. These containers are resource-isolated, virtualized operating systems. They make it easier to package code, manage configurations, and network efficiently.
Containers require management services as managing them can be arduous and too complex for an IT team to handle. To efficiently manage containers, organizations use container management software solutions.
Containers run on a single shared operating system. Conversely, virtual machines (VMs) package multiple applications, each with its own operating system. Based on the IT requirements, containers can run on bare-metal servers or in the cloud.
The container architecture doesn’t incorporate hypervisors or server virtualization software, which makes VMs possible. In fact, it’s more feasible to host a larger number of containers than VMs on a single host. Containers help businesses package applications for better portability, scalability, and effortless deployment. Unlike VM hosting, containers can scale on their own when needed. Sharing a single operating system increases interoperability as well.
Container management solutions help users keep track of individual packages, along with their versions and connections. The flexible, scalable nature of containerized applications improves a product’s range of functionality and simplifies administration requirements such as resource allocation and scaling. They also typically support multiple languages and frameworks.
Container management tools are available as both open-source and proprietary products. Companies use these tools to build and deploy entire applications or deliver module-based application components. With container management software, companies can automate deployments, manage connections, and control each version of their offering.
Containers contain not just the application. Instead, it has everything that it needs to run, including system libraries, necessary executables, configuration files, and more. They are scalable, easy to share, and can run across multiple platforms. The following are some of the core features of container management systems:
Virtualization: Container management software virtualizes operating systems and nests virtualizations within a contained environment.
Datacenters: The software integrates data with container contents and applications.
Architecture: Container management tools create integrations and allow the management of connected containers.
Developer toolkit: These software solutions provide tools for developers to build software and edit container contents.
Orchestration: These tools run applications through connected clusters.
Container networking: Container management software can help define container connections, balance loads, and organize routes.
Auto-scaling: This feature of container management solutions help determine and manage the hardware requirements and space needed automatically and instantaneously.
Packaging: Container management solutions can help group containers or applications without altering the container contents.
File isolation: This feature of container management tools isolates containers based on components of the file systems and their state.
Network isolation: Container management software separates containers based on their specific network and connections.
Cluster management: This feature of container management tools is useful to manage containers grouped together in pods.
Access control: These tools also allow administrators to control access to specific containers or datasets.
If an organization relies on a large number of containers, it’s nearly impossible for DevOps teams to handle them manually. For that reason, companies can rely on software to manage them. The following are some of the notable benefits of using container management tools:
Ease of management: Container management solutions can automate the installation, management, and scaling of containerized applications, services, and workloads.
Consistency: Container management platforms offer improved consistency via two paths. The first is their resource-independent nature. This means individual containers can be updated, deployed, or destroyed without affecting other application components. The second is through version control. Container management systems have organizational components to manage and store containers. Many also provide monitoring and reporting capabilities to keep track of changes and deployments.
Efficiency: Efficiency relates back to the resource-independent nature of containerized code. The container architecture saves time when developing and scaling applications by keeping each component functional on its own. The ability to make changes and add functionality without disrupting an application’s entire ecosystem promotes rapid development and testing practices. Companies and development teams can quickly test new features, modules, plugins, or integrations without changing the user’s overall experience or restricting access for a period of time.
Container security: An isolated application is typically a more secure application. Companies deploying containerized applications can connect their services to third-party applications with a reduced risk of jeopardizing their internal application security. While the connected applications may be interacting, they will not compromise information from the company’s network.
Fault tolerance: With container management software, containers are isolated and operate independently. This means that a failure in a container doesn’t affect other containers, ultimately reducing downtime.
IT administrators: IT administrators use container management systems to create, deploy, and manage containers. It can help them allocate resources efficiently, balance system workloads, and automate container execution.
Developers: Developers can use container management tools to launch, test, and secure apps in resource-independent environments. They can use the software to streamline container performance and ultimately enhance the performance of widely distributed applications. Additionally, containers make it easy for developers to reuse code and secure apps.
Related solutions that can be used together with container management software include:
Container orchestration software: Container orchestration solutions help automate the process of running containerized workloads and services, linking containers, and provisioning hosts. More precisely, these tools help with container lifecycle management and assist in optimizing orchestration procedures.
Container engine software: Also known as operating-system-level virtualization, they are operating systems in which the kernel allows multiple isolated instances. These tools simplify migration processes and enable developers to separate apps, programs, or code segments for enhanced security.
Container monitoring software: Container monitoring tools help track container performance and resource usage and collect event data for future analysis. These tools serve as the application performance monitoring tools for container-based applications. They enable companies to perform real-time monitoring and can help prevent large-scale failures.
Container networking software: As the name suggests, container networking software enhances the functionality of container management software by creating a virtualized network that enables container-to-container connectivity.
Container registry software: This software enables users to manage containers distributed across their applications and networks. It pushes containers to container management solutions and helps organize and find individual containers.
Continuous integration tools: Continuous integration tools help developers automatically integrate the code changes from multiple contributors into a single project. These tools can perform tests against newly written code and also shows the lists of passed and failed tests.
Runtime software: Container runtime tools help companies manage the container application lifecycle and launch apps. They combine container images, file systems, and configurations and enable users to set access policies. Organizations can use these tools to specify how file systems are unpacked, built, and configured.
Although container management platforms offer several advantages, it comes with their own set of challenges. The following are some of them:
Security: The compact design of containers makes them susceptible to hacking. Since containers interact with multiple components, the attack surface for hackers expands even further. Additionally, container protection is not very powerful as modules are running on a single browser. However, emerging technologies will have a quick resolution for such issues.
Storage: When containers shut down, all data in them will be erased because containers are designed to be usable only when they’re required. However, specific storage tools for containers can help resolve this issue.
Integration: Although containers are considered independent and isolated units, they typically have to be integrated with APIs and other containers in the ecosystem. Traditional enterprise facilities may have to be modified to support the API implementation or interconnection needed to support a container ecosystem. More precisely, optimizing the underlying IT infrastructure to support containers can be an arduous task.
Before starting the search for a container management solution, it’s crucial to gather the company’s requirements. This could include gathering information about the essential features of the software product.
Although most container management tools will have a set of common features, there can be specialized features that the company requires for its unique use case, for example, GPU support, point and click publishing, or identity management. Understanding and listing such features can help with finding the most suitable product.
The decision about whether to deploy the containers on premises or in a public cloud platform will also affect the purchase decision and cost. On-premises container infrastructure will offer complete control over the container environment. It also provides better flexibility in configuring networks and storage. On the contrary, public cloud-based containers are easier to set up and manage. They’re more scalable as cloud computing resources can be added on demand. Additionally, containers can be hosted in a private cloud, hybrid cloud, or multicloud environments.
Create a long list
Buyers should start with a long list of container management software vendors. This will help determine whether a specific product is appropriate or not. In this phase, the emphasis should be on getting a basic understanding of the types of software solutions available, more than finding the right product. This long initial list can include any software product that meets the organization’s minimum requirements, such as the ability to create and manage containers.
Create a short list
A short list is a refined list that’s derived from the long list of prospective vendors. This shorter list should include container management products that specifically meet the company’s requirements, or in other words, the software products that have the must-have features.
Removing products that don’t fit within the desired price range or structure is a sensible step at this stage. Additionally, products without the additional or nice-to-have features can also be removed from the short list. The products that remain on the short list can be compared based on their pricing, features, usability, and vendor support.
Conduct demos
Conducting demos of container management software with the same use cases can help buyers effectively compare the products in the short list. Demos are great avenues for examining the usability and functionality of the software, checking whether the software features work as expected, and asking vendors questions related to functions or features that matter the most.
Choose a selection team
A selection team is critical to the success of container management system purchase and implementation. The team should include relevant stakeholders of the company who can use the software, scrutinize it, and check whether it will meet its requirements. The individuals responsible for the day-to-day use of container management tools must be part of the selection team. IT administrators, developers, and decision makers could be the primary personas included in the group.
Negotiation
Once the buyer has narrowed it down to a specific product, they must discuss the terms and conditions and negotiate the pricing with the container management software vendor. Buyers should make sure they request the vendors to include only those features that they require. Although vendors may try to convince buyers about the discounts they can avail of by buying more features or licenses in bulk, companies may never use them.
Even if something is written on the vendor’s pricing page, they’re usually negotiable. Vendors may be willing to offer discounts or an extra number of licenses for multi-year contracts. Negotiation on implementation, support, and other professional services are also crucial. Buyers should ensure that they’ll receive adequate support to get the product up and running.
Final decision
Before making the software purchase decision, it’s advisable to test the software for a short period of time. The day-to-day users of the software are the best individuals to perform the testing. They can use and analyze the capabilities of the software product and offer valuable feedback.
In most cases, software service providers offer a short-term trial of the product. If the selection team is satisfied with what the software offers, buyers can proceed with the purchase or contracting process.
The cost of container management software typically depends on the number and type of features required. It can also be based on the number of nodes or instances running per month or year. Additionally, pricing can be based on the virtual CPU and memory resources required for specific tasks.
When calculating the return on investment of container technology, companies can consider key metrics such as frequency of software releases, developer productivity, IT operations productivity, and operational efficiency. Organizations should also consider how much time and effort they’re saving while managing containers with the help of the software.
Containers can help save time as the operating system kernel start-up takes only a few seconds, whereas VMs take minutes. They’re also more efficient and flexible when compared to VMs. High application availability, scalability, and decreased downtime are some of the immediate benefits. Additionally, there will be an increase in infrastructure utilization.
Artificial intelligence for IT operations (AIOps)
AIOps involves automating and enhancing IT operations with the help of machine learning and analytics. AIOps platforms collect data from various IT operation tools to automatically spot issues and increase the accuracy of root cause analysis (RCA). For container management, AIOps can help companies accelerate issue identification and reduce resolution time.
Container security
Several emerging technologies are striving to tackle the common security issues that come with containerization. Machine learning-based anomaly detection and automated vulnerability scanning are two examples.
