Charting Cloud Success with Microsoft: Understanding CAF and WAF

Charting Cloud Success with Microsoft: Understanding CAF and WAF


Microsoft is a major player when it comes to cloud computing, specifically with its two foundational frameworks: the Cloud Adoption Framework (CAF) and the Well-Architected Framework (WAF). The CAF has been instrumental in guiding organisations through their cloud adoption journey, offering a comprehensive array of best practices, documentation, and tools for effective cloud strategy and implementation.

On the other hand, the WAF, while not a recent introduction, has received substantial updates to further enhance cloud architecture approaches. These updates, particularly in late 2023, reflect Microsoft’s commitment to continuous improvement, ensuring that the framework remains relevant and valuable in addressing the evolving needs of cloud architecture.

Explore why CAF and WAF are the commonly discussed and implemented frameworks, gain in depth overview on their significance for businesses navigating the complexities of cloud transformation.

What is CAF and how does it work?

The Microsoft Cloud Adoption Framework (CAF) is not just a blueprint for cloud adoption; it’s an evolving guide that adapts to the ever-changing cloud landscape. This framework is meticulously designed to support cloud architects, IT professionals, and business decision-makers in seamlessly transitioning to the cloud. It aligns business objectives with technical strategies, ensuring successful cloud adoption and optimisation. The CAF encompasses a full lifecycle approach, addressing each stage of cloud adoption with detailed methodologies:

  • Strategy: This involves understanding the underlying motivations for cloud adoption and clearly defining the desired business outcomes. It’s about setting a solid foundation for the cloud journey by aligning it with business objectives.
  • Plan: Here, the focus is on developing actionable and strategic plans that align with the set business goals. This phase involves detailed planning for the cloud adoption process.
  • Ready: This step prepares the cloud environment to accommodate upcoming changes, ensuring it’s optimised and aligned with the planned adoption strategies.
  • Migrate: This critical phase involves the migration and modernisation of existing workloads to the cloud. It includes strategies for both moving existing applications and rearchitecting them in a cloud-native environment.
  • Innovate: Encouraging the development of new, cloud-native or hybrid solutions, this phase fosters innovation and leverages the full potential of cloud capabilities.
  • Secure: Recognising the importance of security, this methodology focuses on enhancing security measures and ensuring robust protection of cloud resources.
  • Manage: This entails the management and operational oversight of cloud and hybrid solutions, emphasising efficiency and performance optimisation.
  • Govern: It involves the governance of the cloud environment and workloads, ensuring compliance, risk management, and alignment with business policies.

Recent updates to the CAF include a stronger emphasis on sustainability, multi-tenant architectures, and integration with systems like Systems Applications and Products In data Processing (SAP). These updates reflect Microsoft’s commitment to providing a framework that not only guides but also grows with the technological advancements and changing business landscapes.

What is WAF and how does it work?

The Well-Architected Framework (WAF) by Microsoft, while not a brand-new introduction, has recently undergone significant enhancements to further strengthen its role in cloud architecture. Complementing the Cloud Adoption Framework (CAF), WAF focuses intently on the architectural aspect of cloud solutions, guiding the design and management of cloud-hosted applications to ensure they are robust, secure, cost-efficient, and high-performing. The framework is structured around five key pillars, each representing a core element of architectural excellence:

  • Reliability: This pillar emphasises the creation of systems that are not only resilient but also capable of swift recovery in the face of disruptions. The goal is to ensure uninterrupted service and high availability.
  • Security: Focused on safeguarding applications and data, this pillar involves implementing comprehensive security measures that protect against threats while maintaining compliance and privacy standards.
  • Cost Optimisation: Balancing cost against performance and capacity, this area aims to optimise resource utilisation and expenditure, ensuring that cloud investments are both effective and economical.
  • Operational Excellence: This involves enhancing operational procedures to ensure smooth, efficient, and reliable business processes. It encompasses automation, monitoring, and continuous process improvement.
  • Performance Efficiency: Concentrated on maximising system performance, this pillar stresses the importance of leveraging cloud capabilities to achieve scalable and responsive solutions.

The recent updates to WAF, announced in late 2023, have enriched the framework with more precise guidelines and instructional content across these pillars. These enhancements include updated design principles, checklists, trade-offs, and recommendation guides, all rooted in extensive real-world experience and customer engagements. The framework now offers more detailed guidance for workload teams, shaping discussions and decisions within these teams and setting continuous standards for all workloads.

“Drawing on learnings from over 10,000 engagements, the updated framework contains guidance for making architectural trade-offs in cloud workloads as well as much more precise instruction on how users can implement this guidance within the context of their organisation”. – Microsoft

How does CAF work with WAF?

While CAF provides a broad roadmap for cloud adoption, WAF dives deeper into the architectural design, ensuring that the implemented solutions are not only aligned with business strategies (as CAF ensures) but also are well-architected in terms of performance, security, and cost. WAF essentially fills the gaps in CAF by providing detailed guidance on designing and managing cloud workloads efficiently.

Adopting these frameworks is not just about leveraging technology; it’s about a transformation in delivering IT services and reorienting business strategies. CAF ensures that this transformation is well-grounded in business strategy, while WAF guarantees that the technology implementation is optimal and well-architected. By integrating these frameworks, Oreta helps organisations to “stand on the shoulders of giants” by leveraging Microsoft’s vast experience to avoid common pitfalls and accelerate cloud journeys.

Migrating to cloud? Consider Microsoft Azure

Migrating to cloud? Consider Microsoft Azure

Key points

  • Microsoft Azure gives enterprises the flexibility to start small and grow their infrastructure as their business grows.
  • Enterprises can easily integrate Microsoft apps and services into its existing solutions.
  • Microsoft Azure offers secure cloud solutions by using sophisticated encryption algorithms and techniques.

Australia is at the forefront of cloud adoption. Approximately 95% of organisations are running applications or experimenting with infrastructure as a Service (IaaS), with cloud service providers, such as Microsoft Azure, managing the infrastructure – and for a good reason. They are seeing the benefits of migrating their apps and workloads to the cloud.

Microsoft Azure (‘Azure’) is one of the fastest growing and most secure cloud infrastructure platforms available today. It is renowned for its speed, flexibility, and resilience. It boasts the highest amount of security and privacy certifications of any cloud provider. Azure empowers workers to be more productive, enables cognitive learning and AI, and can ultimately transform businesses.

Here our cloud specialist, Dev G, digs a bit deeper into the benefits your business could experience shifting to Microsoft Azure.


Ability to scale on demand.

Cloud infrastructure is hugely beneficial to organisations looking to shift workloads to an expandable pool of resources that can contract and enlarge as demand requires; Azure is no exceptionAzure scales alongside an enterprise’s current needs, Enterprises can monitor and tailor their cloud usage as per their workload requirements in a secure environment with no limitation on server capacity. Thus, giving them the flexibility to augment their infrastructure at a pace that suits their business needs.

Azure can also be set up to auto scale as workloads change. With greater scalability, enterprises can gain the experience and confidence in operating their business in the cloud as they continue to grow, while only paying for what they use.

Tip – To make the most of Azure’s hyper-scale environment and avoid unnecessary costs, enterprises should avoid making the common mistake of ‘just’ migrating from on-premises to the cloud. Enterprises need to continue to monitor Azure once they have migrated to the platform. There are helpful tools, such as Azure Advisor and Azure’s auto-scaling engine, to help set triggers to analyse the environment, including workload behaviour, and create sanctions for availability, performance, security, and cost. 

Greater Flexibility 

In the dynamic technology sector, enterprises need to partner with a host that can evolve as quickly as their needs do. Azure can easily adapt to an enterprise’s unique business needs and provides the capability to manage, deploy and control infrastructure from almost anywhere, at any time, enabling enterprises to modify the cloud as required.

Tip – When adopting Azure, enterprises need to scrap the ‘lift and shift approach. They need to see Azure as a highly scalable and adaptable solution that can be right-sized to their specific and current needs – such an approach will lead to many cost savings. 


More Availability 

Azure features an industry-leading SLA and more than 10,000 Availability Zones enabling businesses to migrate their workloads seamlessly from one locality to another.

Tip – Enterprises need to be mindful that the availability is not built-in to Azure by default. Just because it is in the cloud does not mean a resource is always available. It is important workloads enterprises can access their workloads from more than one virtual machine within the same availability zone (to achieve a high SLA).


Improved Accessibility

Azure offers enterprises the freedom to access services from any device and any location in a secure environment. Azure enables enterprises to easily integrate Microsoft apps and services into their existing solutions. Enterprises can also use the Microsoft Azure App service to write apps that use all the platform’s capabilities, including app storage, networking, servers, storage, database, analytics, and machine learning.


Robust Security 

Azure offers several secure cloud solutions which use sophisticated encryption algorithms and techniques. When users access Microsoft cloud services, they can retain complete control of their data while remaining fully protected. Azure’s also gives enterprises the flexibility to choose which apps they want to use, the level of encryption to employ and other settings.

Tip – Enterprises need to ensure they have the right security and backup levels in place when they move to Azure – ultimately, it is their responsibility regardless of if the workloads are on-premises or in the cloud. Enterprises also need to extend their continuity strategy, processes and tools to include Azure – there are various storage and backup tools available. 


Ability to optimise costs 

Many customers have no idea what discounts or entitlements are available with Microsoft Azure and therefore miss out on huge cost savings. With Microsoft’s huge customer base, it has been able to offer discounted prices to its customers. As the market gets more competitive with AWS and Google, costs will likely go down even further. Also, Azure provides a ‘pay what you use’ model, which significantly reduces the upfront costs for small businesses.

Tips – Azure subscriptions should align with an enterprise’s business goals. Governance tools such as Azure Scaffold can be a powerful cost-management tool, helping enterprises protect businesses from human errors, tag resources, set up policies, quickly run reports on various resources and reduce susceptibility to vulnerabilities which could lead to costly mistakes in the future. 

A great way to optimise your costs with Azure is to shut down machines that are not mission-critical when they are not in use (e.g., after-hours). If you are using a subscription model and not paying upfront for virtual machines, you don’t need to have your infrastructure operating 24 x7.  


Platform as a Service (PaaS) 

Another core strength of Azure is its Platform as a Service (PaaS) capability. Completely serverless, enterprises do not have to worry about infrastructure, including monitoring patching or remediating the server. Enterprises do not have to waste time on deploying, configuring, managing, and monitoring IaaS infrastructure Their IT team can spend more time on the business’s strategic aspects; helping it grow and succeed and save on time and money.

Tip – Enterprises must select which workloads they want to move to PaaS as not all workloads are suitable for this environment.


Hybrid Capability 

Azure allows enterprises to build hybrid environments, enabling them to take advantage of on-premises resources and the benefits of operating on a cloud platform without any hidden unnecessary costs.

Azure continues to grow rapidly, regularly adding support for various features, applications and different technology platforms. If you are considering migrating to the cloud, Azure should be on the list of options.


Oreta has gold partner status with Microsoft because of its distinctive competencies in Azure, including system integration and managed services. We partner with customers throughout their journey to the cloud – from advisory and delivery to operations and continued optimisation.


What’s Multi-Cloud?

What’s Multi-Cloud?

Multi-cloud is the use of more than one cloud platform that each delivers a specific application or service. A multi-cloud architecture can be made up of two or more public or private clouds to achieve a business’s IT goals. 

What is the difference between hybrid cloud and multi-cloud?

There are several distinct differences between Hybrid cloud and multi-cloud architectures.

Traditionally ‘Hybrid cloud’ has meant the combination of private (either on-premises or hosted in a datacentre) and public cloud infrastructure, with application tools used to orchestrate and deploy workloads and manage the balance between the two.

Multi-cloud by contrast has more of a strategic emphasis. Enterprises use multiple cloud providers to meet different business requirements. At its most granular, multi-cloud is made up of various IaaS, PaaS and SaaS services with the cloud-native applications being the most mature, which are built up from containers and microservices, and provided by different cloud providers.

The main difference between the two is ‘Hybrid cloud’ refers to multiple cloud platforms, multi-cloud refers to multiple cloud services or vendors.

Benefits of a multi-cloud approach?

Many businesses nowadays have adopted a multi-cloud strategy by deploying applications and services across several cloud environments.  There are many reasons for this, including:

Remove Vendor Lock-In – one of the most common reasons organisations adopt a multi-cloud strategy is the desire not to lock into any particular cloud provider. Enterprises recognise that no one provider can be everything to everyone. A multi-cloud approach gives organisations the flexibility to identify and partner with the vendors that have best-of-breed solutions that best align to their business needs.

Improved Performance – organisations with a wide range of cloud-based workloads can minimise latency and other performance barriers, such as packet loss, by investing in multiple cloud providers closest to where the applications and users are.

Compliance Management– Data governance often requires customer data to be held in different locations. Using a multi-cloud strategy improves adherence to such policies.

High Availability and Resilience – All cloud providers, even hyperscale ones with multiple geographically dispersed, redundant datacentres – suffer outages from time to time. If organisations put their dependency only on one cloud provider, they run the risk of their mission-critical applications becoming unavailable. A multi-cloud strategy allows for better security, failover, and disaster recovery – and resilience.


Although a multi-cloud strategy has its advantages such as greater flexibility and scalability, it can also cause complexity in deployment and management, including:

  • Security and governance are more complicated. There are more “moving parts” which may create resiliency issues.
  • Organisations could suffer a paradox of choice when having to select the right cloud products and services.
  • Management complexity could become a problem especially if multi-cloud is adopted in an ad hoc manner rather than been planned from the ground up.
  • Organisations could experience perimeter dissolution.In a single cloud environment, it is easy to build a perimeter to protect sensitive data and workloads which are residing in the same cloud. With a multi-cloud approach, data is spread across multiple cloud locations, making it easier to access, traverse across different cloud locations and blur the lines. Therefore, strategies zero-trust become imperative to implement.
  • A multi-cloud approach does not provide the same level of visibility as a single cloud environment. As underline infrastructure becomes more abstract, as more clouds are adopted, operation levels could reduce as does the level of visibility and control.
  • Organisations need to dedicate significant time monitoring all their assets (e.g., cloud functions) and resources across their entire multi-cloud environment, especially as modern software architecture continues to evolve, and their life span becomes shorter.
  • As every cloud operates differently, organisations need to have robust policy and access control protocols to protect their data and workloads. Organisations need to be able to uniformly apply these policies and access control across their entire cloud environment.

Is a multi-cloud strategy right for you?

Cloud computing adoption is well established in enterprises, SMEs, and start-ups. But how much cloud should a business adopt? How should workloads be deployed across public, private, and hybrid clouds? And if multiple cloud providers (public and/or private) are used, which ones should you choose, and how can they be managed to a business’s best advantage? These are all questions organisations need to consider when determining what cloud strategy they will deploy.
