1. Introduction
Infrastructure as a Service (IaaS) virtualization presents significant advantages for organizations seeking to enhance their agility, flexibility, and speed to market within the DevOps and continuous delivery frameworks. Addressing the associated risks and challenges is crucial and can be achieved by employing the appropriate monitoring and testing techniques, enlisted further, in this blog.
IaaS virtualization allows organizations to provision and de-provision resources as needed, eliminating the need for long-term investments in hardware and data centers. Furthermore, IaaS virtualization offers the ability to operate with multiple operating systems, databases, and programming languages, empowering teams to select the tools and technologies that best suit their requirements.
However, organizations must implement comprehensive testing and monitoring strategies, ensure proper security and compliance controls, and adopt the best resource optimization and management practices to leverage the full potential of virtualized IaaS. To achieve high availability and fault tolerance along with advanced networking, enabling complex application architectures in IaaS virtualization, the blog mentions five industry tips.
2. What is IaaS Virtualization?
IaaS virtualization involves simultaneously running multiple operating systems with different configurations. To run virtual machines on a system, a software layer known as the virtual machine monitor (VMM) or hypervisor is required.
Virtualization in IaaS handles website hosting, application development and testing, disaster recovery, and data storage and backup. Startups and small businesses with limited IT resources and budgets can benefit greatly from virtualized IaaS, enabling them to provide the necessary infrastructure resources quickly and without significant capital expenditures.
Virtualized IaaS is a potent tool for businesses and organizations of all sizes, enabling greater infrastructure resource flexibility, scalability, and efficiency.
3. Virtualization Techniques for DevOps and Continuous Delivery
Virtualization is a vital part of the DevOps software stack. Virtualization in DevOps process allows teams to create, test, and implement code in simulated environments without wasting valuable computing resources. DevOps teams can use the virtual services for thorough testing, preventing bottlenecks that could slow down release time. It heavily relies on virtualization for building intricate cloud, API, and SOA systems. In addition, virtual machines benefit test-driven development (TDD) teams that prefer to begin their troubleshooting at the API level.
4. Integration of IaaS with CI/CD Pipelines
Continuous integration is a coding practice that frequently implements small code changes and checks them into a version control repository. This process not only packages software and database components but also automatically executes unit tests and other tests to provide developers with vital feedback on any potential breakages caused by code changes.
Continuous testing integrates automated tests into the CI/CD pipeline. For example, unit and functionality tests identify issues during continuous integration, while performance and security tests are executed after a build is delivered in continuous delivery. Continuous delivery is the process of automating the deployment of applications to one or more delivery environments.
IaaS provides access to computing resources through a virtual server instance, which replicates the capabilities of an on-premise data center. It also offers various services, including server space, security, load balancing, and additional bandwidth. In modern software development and deployment, it's common to integrate IaaS with CI/CD pipelines. This helps automate the creation and management of infrastructure using infrastructure-as-code (IAC) tools. Templates can be created to provision resources on the IaaS platform, ensuring consistency and meeting software requirements. Additionally, containerization technologies like Docker and Kubernetes can deploy applications on IaaS platforms.
5. Considerations in IaaS Virtualized Environments
5.1. CPU Swap Wait
The CPU swap wait is when the virtual system waits while the hypervisor swaps parts of the VM memory back in from the disk. This happens when the hypervisor needs to swap, which can be due to a lack of balloon drivers or a memory shortage. This can affect the application's response time. One can install the balloon driver and/or reduce the number of VMs on the physical machine to resolve this issue.
5.2. CPU System/Wait Time for VKernel
Virtualization systems often report CPU or wait time for the virtualization kernel used by each virtual machine to measure CPU resource overhead. While this metric can't be directly linked to response time, it can impact both ready and swap times if it increases significantly. If this occurs, it could indicate that the system is either misconfigured or overloaded, and reducing the number of VMs on the machine may be necessary.
5.3. Memory Balloon
Memory ballooning is a memory management technique used in virtualized IaaS environments. It works by injecting a software balloon into the VM's memory space. The balloon is designed to consume memory within the VM, causing it to request more memory from the hypervisor. As a result, if the host system is experiencing low memory, it will take memory from its virtual infrastructures, thus negatively affecting the guest's performance, causing swapping, reduced file-system buffers, and smaller system caches.
5.4. Memory Swap Rate
Memory swap rate is a performance metric used in virtualized IaaS environments to measure the amount of memory being swapped to disk. When the swap rate is high, it leads to longer CPU swap times and negatively affects application performance. In addition, when a VM is running, it may require more memory than is physically available on the server. In such cases, the hypervisor may use disk space as a temporary storage area for excess memory. Therefore, to optimize, it is important to ensure that VMs have sufficient memory resources allocated.
5.5. Memory Usage
Memory usage refers to the amount of memory being used by a VM at any given time. Memory usage is assessed by analyzing the host level, VM level, and granted memory. When memory usage exceeds the available physical memory on the server, the hypervisor may use disk space as a temporary storage area for excess memory, leading to performance issues. The disparity between used and granted memory indicates the overcommitment rate, which can be adjusted through ballooning.
5.6. Disk/Network Latency
Some virtualization providers provide integrated utilities for assessing the latency of disks and network interfaces utilized by a virtual machine. Since latency directly affects response time, increased latency at the hypervisor level will also impact the application. An excessive amount of latency indicates the system is overloaded and requires reconfiguration. These metrics enable us to monitor and detect any negative impact a virtualized system might have on our application.
6. Industry tips for IaaS Virtualization Implementation
Testing, compliance management and security arecritical aspects of managing virtualized IaaS environments . By implementing a comprehensive strategy, organizations ensure their infrastructure and applications' reliability, security, and performance.
6.1. Infrastructure Testing
This involves testing the infrastructure components of the IaaS environment, such as the virtual machines, networks, and storage, aiming to ensure the infrastructure is functioning correctly and that there are no performance bottlenecks, security vulnerabilities, or configuration issues. Testing the virtualized environment, storage testing (testing data replication and backup and recovery processes), and network testing are some of the techniques to be performed.
6.2. Application Testing
Applications running on the IaaS virtual environment should be thoroughly tested to ensure they perform as expected. This includes functional testing to ensure that the application meets its requirements and performance testing to ensure that the application can handle anticipated user loads.
6.3. Security Monitoring
Security monitoring is critical in IaaS environments, owing to the increased risks and threats. This involves monitoring the infrastructure and applications for potential security threats, vulnerabilities, or breaches. In addition, regular vulnerability assessments and penetration testing help identify and address potential security issues before they become significant problems.
6.4. Performance Monitoring
Performance monitoring is essential to ensuring that the underlying infrastructure meets performance expectations and has no performance bottlenecks. This comprises monitoring metrics such as CPU usage, memory usage, network traffic, and disk utilization. This information is used to identify performance issues and optimize resource usage.
6.5. Cost Optimization
Cost optimization is a critical aspect of a virtualized IaaS environment with optimized efficiency and resource allocation. Organizations reduce costs and optimize resource usage by identifying and monitoring usage patterns and optimizing elastic and scalable resources. It involves right-sizing resources, utilizing infrastructure automation, reserved instances, spot instances (unused compute capacity purchased at a discount), and optimizing storage usage.
7. Conclusion
IaaS virtualization has become a critical component of DevOps and continuous delivery practices. To rapidly develop, test, and deploy applications with greater agility and efficiency by providing on-demand access to scalable infrastructure resources to Devops teams, IaaS virtualization comes into picture. As DevOps teams continue to seek ways to streamline processes and improve efficiency, automation will play an increasingly important role. Automated deployment, testing, and monitoring processes will help reduce manual intervention and increase the speed and accuracy of development cycles. In addition, containers will offer a lightweight and flexible alternative to traditional virtualization, allowing DevOps teams to package applications and their dependencies into portable, self-contained units that can be easily moved between different environments. This can reduce the complexity of managing virtualized infrastructure environments and enable greater flexibility and scalability. By embracing these technologies and integrating them into their workflows, DevOps teams can achieve greater efficiency and accelerate their delivery of high-quality software products.

1. Introduction
Several leading companies are providing IaaS platforms, offering managed and unmanaged services, and multi-cloud and hybrid cloud solutions to meet the growing demands of businesses in today's digital landscape. In addition, these companies offer various services to help organizations manage their IT infrastructure, including computing power, virtual machines, storage, and networking, while also providing additional value-added services such as security, disaster recovery, and automation.
2. Multi-Cloudvs. Hybrid Cloud
Multi-cloud and hybrid cloud are cloud deployment infrastructure models
2.1. Multi-Cloud Storage Systems:
Multicloud refers to an organization utilizing cloud computing services from at least two cloud providers to run their applications. Instead of relying on a single-cloud stack, multi-cloud environments usually consist of two or more public clouds, two or more private clouds, or a mix of both.
2.2. Hybrid Cloud Storage Systems:
A hybrid cloud refers to a heterogeneous computing environment where applications are executed using a blend of computing, storage, and services across distinct environments, such as public clouds, private clouds, on-premises data centers, or edge locations.
2.3. Choosing Between Multi-Cloud and Hybrid Cloud
2.3.1. Opting for a Hybrid Cloud:
For businesses that require control over certain data or workloads, a hybrid cloud strategy may be necessary. This involves hosting some applications in the public cloud while running critical workloads locally to balance the benefits of cloud technology with the need for local data control. - To avoid vendor lock-in, carefully select the best cloud services for each application or task. - Choose cost-effective services to engage in more effective business planning. - Ensure flexibility and adaptability for the cloud team. - Enable a company to use best-in-class services for each app/task
2.3.2. Selecting a Multi-Cloud:
Businesses often rely on multiple cloud providers for different services, such as public clouds for virtual machines and SaaS for business applications. They may also access AI, ML, or language cloud services from other providers. - To test and validate a cloud computing platform before migrating its resources and workloads. - To enable a centralized identity infrastructure across disparate systems. - To ensure a blend of self-service resources (private cloud) and a platform to run test workloads (public cloud), for DevOps based firms However, hybrids and multi-clouds can operate together. For example, a company can establish a private cloud for internal operations and then merge it with a public cloud to form a hybrid cloud. Additional clouds, whether IaaS, PaaS, or SaaS, can be added or integrated to provide specific resources or services to the business. Alternatively, a company can create a hybrid cloud with one public cloud provider and still use resources and services from other public clouds outside the hybrid cloud environment.
3. Managed and Unmanaged Services
IaaS comes in two main forms: managed and unmanaged. Managed services can simplify server maintenance by providing support and expertise. With managed dedicated servers, clients can focus on other aspects of their business while the host takes care of day-to-day maintenance, including software upgrades. This option is also safer, as self-managing a server without the necessary expertise can create security vulnerabilities. Unmanaged services are cheaper but don't include extras or support. Standard or custom control panels are used for task management. However, managing servers can only be done with experience. In addition, unmanaged hosting services are limited to providing a default solution configuration, and the applications must be installed on the cloud server by the user.

Hyper-Converged Infrastructure, IT Systems Management
Article | September 14, 2023
With infrastructure as code (IaC), you write declarative instructions about compute, storage and network requirements for the infra and execute it. How does this compare to platform as code (PaC) and what did these two concepts develop in response to? In its simplest form, the tech stack of any application has three layers — the infra layer containing bare metal instances, virtual machines, networking, firewall, security etc.; the platform layer with the OS, runtime environment, development tools etc.; and the application layer which, of course, contains your application code and data. A typical operations team works on the provisioning, monitoring and management of the infra and platform layers, in addition to enabling the deployment of code.
