For the majority of businesses, digital transformation (DX) has emerged as a significant priority. By incorporating digital technologies into all aspects of an organization's operations, digital transformation is a continuous process that alters how organizations operate as well as how they supply goods and services to customers and connect with them.
Employing hybrid network infrastructures can aid businesses in putting DX strategies into action. An IT architecture and environment is a hybrid infrastructure that combines on-premises data centers with private or public clouds. Operating systems and applications can be deployed anywhere in this environment, depending on the needs and specifications of the firm.
Managing and keeping an eye on an organization's whole IT infrastructure requires the use of hybrid IT infrastructure services, sometimes referred to as cloud services. Given the complexity of IT environments and needs, this is essential for digital transformation.
What Does Hybrid Network Infrastructure Have To Offer?
Flexibility
Companies can employ the appropriate tools for the job, thanks to flexibility. For instance, a business needs access to a lot of data if it wants to use machine learning (ML) or artificial intelligence (AI). Utilizing public cloud services like AWS or Azure can help with this. However, these services might be pricey and not provide the performance required for some applications.
Durability
Hybrid networks are more tolerant of interruptions. For instance, a business can continue to function if there is a problem with its public cloud by using its private data center. This is due to the fact that the outage in the public cloud has no impact on the private data center.
Security
Businesses can utilize a hybrid cloud strategy to protect sensitive data while utilizing the resources and services of a public cloud, potentially lowering the chance of crucial information being compromised. While analytics and applications that use data kept in a private environment will probably still need to function in a public cloud, you can use encryption techniques to reduce security breaches.
Scalability and Efficiency
Traditional networks can't match the performance and scalability of hybrid networks. This is due to the fact that public clouds offer enormous bandwidth and storage that may be used as needed. By using a hybrid architecture, a company can benefit from the public cloud's flexibility and capacity while still keeping its business-critical data and operations in the private cloud or on-premises data center.
Conclusion
A cultural shift toward more flexible and intelligent ways of conducting business, supported by cutting-edge technology, involves integrating digital technologies throughout all company activities, improving current processes, developing new operational procedures, and offering higher value to clients. Infrastructures for hybrid networks are necessary for the success of digital transformation.

The year of the pandemic – that is how many of us will remember 2020 for generations to come. Challenging circumstances brought by the sudden and devastating spread of coronavirus (COVID-19) has made us witness the world making quick changes to remote working, businesses struggling to survive, the distress of social distancing rules, the emotional rollercoaster for people isolating, an overall crisis for health systems and the economy of countries, no matter where you were in the world.
When reflecting on what it has meant so far, however, we must realise that it’s not all doom and gloom. As Albert Einstein once said, “in the midst of every crisis lied a great opportunity”. The crisis has prompted companies to reinvent and accelerate digital plans, to adopt new technologies and sales models in order to adapt and survive – and for Managed Service Providers (MSPs) to step up to support businesses and employees in every way possible.
On the other hand, let’s also not forget what the changes have meant for the health of our ecosystems. With industries across varied sectors forced to work remotely and shut down operations, the changes have led to benefits for the environment – and we could argue that such break was something that our planet was desperately in need of.
Even now, as we start to see our way out of this situation, it’s hard to believe how it all happened. For most countries, it was a similar case: we were hearing news about a new virus spreading in China; and before we knew more about it, the virus arrived in our own territories. It seemed unlikely, and yet, a few days later, the virus was quickly spreading, and lockdown restrictions came into effect for almost every nation in the globe. Millions of workers around the world had to leave the office and make a quick switch to remote working, without much notice at all.
In the initial stages of lockdown, MSPs had to work around the clock to help customers that weren’t ready for flexible working, to enable people to work from home. As every other industry and business type, MSPs also encountered challenges. Not being able to help a client on-site can sometimes significantly affect the speed of project delivery. So, adjustments had to be made, wherever possible, to deliver services remotely, as quickly and seamlessly as possible.
“We are all in this together” is a phrase that became widespread in the UK. IT professionals, like many other sectors, had to support each other, and they have been working together as a community, to assist clients, businesses, and the wider public, since working from home was suddenly imposed for the vast majority. In the technology space, there is a lot of knowledge to share and to work with, which has led to many tech leaders and companies offering free advice, webinars and other tools to help with the struggles that have risen in the midst of the pandemic.
Shifting priorities based on customer needs
In the initial stages of the pandemic, MSPs played a critical role providing small and medium sized businesses with the tools and the IT infrastructure to keep their business running. Enabling office-based workers to continue their work from home was only the first step, however.
The sudden shift to remote working has required new tools and exposed new security vulnerabilities. All around the world, we saw an increasing number of cyber-attacks and threats taking place. Remote working means many people were using personal computers for work and business purposes, and so, products that are designed to keep personal computers protected became essential.
MSPs have also focused on increasing security measures for protecting password and identities for customers. Passwords on their own are not secure enough and can be easily compromised, so it has been a case of quickly deploying password management and Multi-factor Authentication (MFA), also known as two-factor authentication (2FA). MFA immediately increases security and ensures that clients’ accounts are significantly less likely to be compromised. In a few simple steps, IT providers can deploy MFA to help protect an organisation against breaches due to lost or stolen credentials.
Beyond helping employees to work from home securely, MSPs have assisted companies in implementing cloud-based applications, and managing access and restrictions to certain applications, especially for furloughed staff.
Embracing opportunities in the post-pandemic landscape
The spread of Covid-19 has made remote working the new norm, but how likely is this to become a permanent thing? Many employers and workers have started to believe that working from home will become more and more common for employees, even after the threat of the virus is gone. It’s difficult to know what the final picture will be, but it’s remains a fact that, as offices gradually re-open after lockdown, employers are increasingly looking at new ways of flexible working.
Many organisations that have been forced to work from home have been functioning remotely with little to no issue, so it stands to reason that the future of work will become more flexible. Video-calls, online training sessions, webinars, online meetings, it all sounds too familiar now, doesn’t it?
Remote working was already popular, though for a long time it wasn’t much more than a much-appreciated working benefit offered by employers, as part of the ‘job perks’ package. The pandemic only accelerated the need for remote working capabilities, and now telecommuting seems to be taking over as the new norm.
The IT landscape has mutated, and quite possibly it has changed for good. Technology leaders will have to continue to listen to the evolving needs and demands of the users and the markets in which they operate. For MSPs, it means the crisis is bringing opportunities to provide value to clients seeking support for enhanced mobility and flexible working. Now that work-from-home setups are in place, there’s room for improving remote access solutions and security measures.
Cloud migrations, which are expected to increase after the pandemic, present an opportunity for remote employees to improve collaboration and business resiliency. There will be a push towards more robust cloud-based solutions, and these migrations are likely to become one of the top opportunities for the months to come to drive revenue for MSPs, as well as VoIP solutions, business continuity and hardware sales.
The pandemic seems to have accelerated the demand for cloud services and security solutions. MSPs will play an important role in finding the best solutions for every business type, to enable them to work more flexibly and effectively. IT providers will be increasingly tasked with the job of securing devices and protecting employees as they work remotely, especially for SMBs.

Introduction
It is hard to manage a modern firm without a convenient and adaptable IT infrastructure. When properly set up and networked, technology can improve back-office processes, increase efficiency, and simplify communication. IT infrastructure can be utilized to supply services or resources both within and outside of a company, as well as to its customers. IT infrastructure when adequately deployed aids organizations in achieving their objectives and increasing profits.
IT infrastructure is made up of numerous components that must be integrated for your company's infrastructure to be coherent and functional. These components work in unison to guarantee that your systems and business as a whole run smoothly.
Enterprise IT Infrastructure Trends
Consumption-based pricing models are becoming more popular among enterprise purchasers, a trend that began with software and has now spread to hardware. This transition from capital to operational spending lowers risk, frees up capital, and improves flexibility. As a result, infrastructure as a service (IaaS) and platform as a service (PaaS) revenues increased by 53% from 2015 to 2016, making them the fastest-growing cloud and infrastructure services segments. The transition to as-a-service models is significant given that a unit of computing or storage in the cloud can be quite cheaper in terms of the total cost of ownership than a unit on-premises.
While businesses have been migrating their workloads to the public cloud for years, there has been a new shift among large corporations. Many companies, including Capital One, GE, Netflix, Time Inc., and others, have downsized or removed their private data centers in favor of shifting their operations to the cloud.
Cybersecurity remains a high priority for the C-suite and the board of directors. Attacks are increasing in number and complexity across all industries, with 80% of technology executives indicating that their companies are unable to construct a robust response. Due to lack of cybersecurity experts, many companies can’t get the skills they need on the inside, so they have to use managed security services.
Future of Enterprise IT Infrastructure
Companies can adopt the 'As-a-Service' model to lower entry barriers and begin testing future innovations on the cloud's basis. Domain specialists in areas like healthcare and manufacturing may harness AI's potential to solve some of their businesses' most pressing problems.
Whether in a single cloud or across several clouds, businesses want an architecture that can expand to support the rapid evolution of their apps and industry for decades. For enterprise-class visibility and control across all clouds, the architecture must provide a common control plane that supports native cloud Application Programming Interfaces (APIs) as well as enhanced networking and security features.
Conclusion
The scale of disruption in the IT infrastructure sector is unparalleled, presenting enormous opportunities and hazards for industry stakeholders and their customers. Technology infrastructure executives must restructure their portfolios and rethink their go-to-market strategies to drive growth. They should also invest in the foundational competencies required for long-term success, such as digitization, analytics, and agile development.
Data center companies that can solve the industry's challenges, as well as service providers that can scale quickly without limits and provide intelligent outcome-based models. This helps their clients achieve their business objectives through a portfolio of 'As-a-Service' models, will have a bright future.

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.
