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.

Edge computing represents the fourth major paradigm shift in modern computing, following mainframes, client/server models, and the cloud. A hybrid architecture of interconnected IaaS services allows for low latency through edge computing and high performance, security, and flexibility through a private cloud. Connecting edge devices to an IaaS platform streamlines location management and enables remote work, thus looking forward to smoother future of IaaS.
An edge layer (fog computing) is required to optimize the architecture model with high-speed and reliable 5G connectivity, connecting edge devices with the cloud. This layer acts as autonomous distributed nodes, capable of analyzing and acting on real-time data. Doing so sends only the data required to the central infrastructure in an IaaS instance. By combining the advantages of edge computing in data capture with the storage and processing capabilities of the cloud, companies can take full advantage of the benefits of data analytics to leverage their innovation and optimization capabilities while simultaneously and effectively managing IoT devices on the edge.
IoT devices, also known as edge devices, possess the ability to analyze data in real time through the use of AI, ML, and algorithms, even in the absence of an internet connection. This technology yields numerous advantages, including superior decision-making, early detection of issues, and heightened efficiency. However, an IaaS infrastructure with top-notch computing and storage capabilities is an absolute necessity to analyze the data effectively.
2.2 Greater Focus on Security
Hackers might use cloud-based services to host malware through malware-as-a-service (MaaS) platforms or to distribute malware payloads using cloud-based apps and services. In addition, organizations often need more than they can secure in their IaaS footprint, leading to increased misconfigurations and vulnerabilities. Recognizing and reacting to an attack is called reactive security, whereas anticipating a dangerous event before it happens and intervening to prevent it is predictive safety. Predictive security is the future of cloud security.
The cybersecurity mesh involves setting up a distributed network and infrastructure to create a secure perimeter. This allows companies to centrally manage access to their data while enforcing security policies across the distributed network. It is a critical component of the Zero-Trust architecture. A popular IaaS cloud security trend is the multi-cloud environment. Multi-cloud proves effective when tools like security information and event management (SIEM) and threat intelligence are deployed.
DevSecOps is a methodology that incorporates security protocols at every stage of software development lifecycle (SDLC). This makes it convenient to deal with threats during the lifecycle itself. Since deploying DevOps, software releases have been shortened for every product release. DevSecOps proves to be secure and fast only with a fully automated software development lifecycle. The DevOps and security teams must collaborate to provide massive digital transformation and security. Digital services and applications need stronger and better security in exponential amounts. This methodology must be enforced in a CI/CD pipeline to make it a continuous process.
Secure access service edge (SASE) is a cloud-based architecture that integrates networking and software-as-a-service (SaaS) functions, providing them as a unified cloud service. The architecture combines a software-defined wide area network (SD-WAN) or other WAN with multiple security capabilities, securing network traffic.
2.3 Enhancement in Serverless Architecture
Serverless architecture apps are launched on demand when an event triggers the app code to run. The public cloud provider then assigns the resources necessary for the operation to occur. With serverless apps, containers are deployed and launched on demand when needed. This differs from the traditional IaaS cloud computing model, where users must pre-purchase capacity units for always-on server components to run their apps.
The app will incur minimal charges during off-peak hours with a serverless model. When there is a surge in traffic, it can scale up seamlessly through the provider without requiring DevOps involvement. A serverless database is a type of database that operates as a fully managed database-as-a-service (DBaaS). It automatically adjusts its computing and storage resources to match the demand, making it convenient for users. A serverless database is a cloud based service that eliminates the need to manage infrastructure, scaling, and provisioning. It allows developers to concentrate on constructing applications or digital products without the burden of managing servers, storage, or backups.
2.4 Evolution of Green Computing
In promoting green computing, infrastructure-as-a-service plays a significant role by allowing cloud providers to manage the infrastructure. This helps reduce the environmental impact and boosts efficiency by intelligently utilizing servers at high utilization rates. As a result, studies show that public cloud infrastructure is typically 2-4 times more efficient than traditional data centers, a giant leap forward for sustainable computing practices.
2.5 Emergence of Containerization
Containerization is a type of operating system virtualization where applications are executed in distinct user spaces called containers. These containers operate on the same shared operating system, providing a complete, portable computing environment for virtualized infrastructure. Containers are self-contained software packages operating in any environment, including private data centers, public clouds, or developer laptops. They comprise all the necessary components required for the right functioning of IaaS-adopted cloud computing.
3. Final Thoughts
With the expansion of multi-cloud environments, the emergence of containerization technologies like Docker and Kubernetes, and enhancements in serverless databases, IaaS is poised to become even more powerful and versatile in meeting the diverse computing needs of organizations. These advancements have enabled IaaS providers to offer a wide range of services and capabilities, such as automatic scaling, load balancing, and high availability, making it easier for businesses to build, deploy, and manage their applications swiftly in the cloud.
