 Cloud Adoption Framework is a set of best practices, tools, and guides that most public cloud vendors publish. The idea behind these cloud adoption frameworks is to assist organizations to embrace public cloud securely, efficiently and faster. The cloud adoption framework comprises each phase of cloud acceptance, from planning to living in the cloud. It provides a very well-tested checklist and steps to choose the right path for cloud migration and the right tools to help reduce potential security, governance, and budget problems. The good thing about the cloud adoption framework is that it covers technological, people, processes and business aspects. Therefore, it helps to align business strategies with the culture, business and technology inspirations to achieve the business benefits. Cloud growth The cloud adoption framework is your guide to making the most of your cloud investment. Most organizations are adopting the cloud as per the IDG’s 2020 Cloud Computing study reveals that 92% of the organizations are somewhat in the cloud. Organizations must adapt to the cloud with proper planning and strategy in place. However, I observe that even if they have the strategy, they have just started consuming the cloud with the migration of simple applications and don’t have any proper framework or rules to follow. Another challenge I am seeing is that organizations don’t have clear visibility to their digital estate. When you start planning about cloud migration or adoption, the first question that comes to mind is to discover or assess the current IT state, which sometimes becomes painful to complete.  Sometimes, what is being observed is that relevant stakeholders don’t know where to start and the requirements or initial checklist they need to follow to migrate to the cloud. According to Gartner, if we map to the trends impacting cloud adoption, there are four critical areas. Cost optimization will drive cloud adoption Multicloud will reduce vendor lock-in  Insufficient cloud IaaS skills will delay migrations Distributed cloud will support expanded service availability There is no doubt that each organization is unique with the operating model, products, services, organizational infrastructure and technology. Now adopting the cloud also depends on the business functions, services and applications are used in the organization; it will be unique to every organization. However, as we are seeing, most organizations are moving to the cloud, so we can say there is a pattern emerging. These frameworks are the results of these patterns concluded from a large number of cloud migrations journeys. Take an example of the work done by the Open Data Center Alliance Cloud Adoption Framework Another paper was presented during the 2017 international conference on information systems and computer science with the name “Unified Cloud Computing Adoption Framework.” which describes the process in six steps framework, current situation definition, requirements definition, providers analysis, providers assessment, decision, and migration. Another interesting and the most I like Enterprise Cloud Adoption Framework developed and shared by the MITRE and targeted areas to address are Political leadership, Organizational, Economic, Technical and Security (POETS) factors.

A deepfake refers to a specific kind of media or photo where a person in an image or video is transacted with another person however it will look like the original person in an image or video. To make a deep fake video, a creator swaps one person’s face and replaces it with another, using a deep learning algorithm generative adversarial networks (GAN). A formal definition as per Wikipedia: Deepfakes are synthetic media in which a person in an existing image or video is replaced with someone else's likeness. While the act of faking content is not new, deepfakes leverage powerful techniques from machine learning and artificial intelligence to manipulate or generate visual and audio content with a high potential to deceive. The main machine learning methods used to create deepfakes are based on deep learning and involve training generative neural network architectures, such as autoencoders or generative adversarial networks (GANs) – Source: Wikipedia Today’s Guest Ilke Demir, Research Scientist at Intel An inspirational talk with the guest speaker on a variety of topics, like How to decide to pursue a short course or a degree program in AI/Data Science, What is a new fake catcher tool? and from where you can find out the number of large datasets.

Cloud migration is challenging, cumbersome, and risky for traditional organizations relying on in-house custom-built systems to support achieving revenue from years on years. Today I will be discussing a wide variety of challenges organizations are facing while planning for cloud migration. These typical challenges are talks of every board room and the agenda of the meetings. However, there is no doubt that workloads migration to the cloud is helping organizations to reduce operating costs and build integrated, automated IT infrastructure. Some Facts on Public Cloud: The global public cloud computing market is continuing to grow, and according to the Statista report of August 4, 2021, it will $482 billion in 2022. IDG’s 2020 Cloud Computing study reveals that 92% of the organizations are somewhat in the cloud. According to the worldwide enterprise cloud strategy 2017-2020 report by Statista, 82% of the respondent reported that they had deployed hybrid cloud strategy in their organizations. Gartner’s global forecast for public cloud end-user spending will grow 23.1% in 2021 to reach $332.3 billion, compares to $270 billion in 2020. (read diagram/table for podcast) Canalys report for the year 2020 that “total cloud infrastructure services spending grew 33% to US$142 billion, up from US$107 billion in 2019.” IDC’s report on global public cloud services $312 Billion in 2020 Cloud computing market report published by marketsandmarkets “The global cloud computing market size is expected to grow from USD 371.4 billion in 2020 to USD 832.1 billion by 2025” Share of corporate data stored in the cloud in organizations worldwide from 2015 to 2021 “As of 2021, around 50 percent of all corporate data is stored in the cloud. This share reached 30 percent in 2015 and has continued to grow as companies increasingly shift their resources into cloud environments in the hope of improving security and reliability next to advancing business agility.“ How to Secure and optimize your cloud migration You have a daunting task in hand to migrate to the cloud and do it securely and efficiently. If it is not fully optimized and performed correctly, your dream of digital transformation in an organization can hit roadblocks/pitfalls. Now I will share some of the common challenges which I see the cloud migrations; these are based on observation, reading a wide array of articles, and discussion with fellow IT friends/colleagues in the extended & broader community of IT professionals. What I will be doing is to mention all the typical challenges, and then I will also try to share the perspective of how you can overcome or what could be the strategy to address them. These could be starting from which workloads to be moved to what should be the order of migration to how we will have reliability and performance of business-critical services on the cloud. How I will implement required levels of security controls and regulatory compliance to who is my cloud vendor and this cloud migration must not disrupt my existing IT services, so on… Gartner, in an article published, has beautifully categorized into six ways of cloud migrations challenge You’ll Learn: Common Cloud Migration Challenges and How to Overcome Them: Why cloud migration is challenging? Some facts on public cloud adoption Common Challenges: Do you have a well-defined & documented Cloud Migration Strategy? How do you see your requirements for Data Security and Compliance? Do you have clarity on the Cost of the Cloud Migration Process? How is your organization's response to adoption/change?

 A cloud migration strategy is a plan which any organization develops to move its systems and applications from on-premises architecture to the cloud.  Not all applications and systems benefit from running on the cloud; that’s why you must indorse the most efficient way to work on it and migrate applications. Therefore, a systematic, documented strategy is essential. Any strategy needs to start from some barefoot, and then it builds on it. Similarly, the vital first step to creating a migration strategy is getting to know what you have? What are the collections of applications, systems, etc.? Once you have documented existing applications, you need to refer to the most common migration strategies. Gartner is calling 5R; some vendors mentioned as 6Rs or 7Rs. (These strategies are: refactor, replatform, repurchase, rehost, relocate, retain, and retire) Your organization will fall in these options, and you need to choose based on the workload discovery/assessment. Rehost refactor revise rebuild replace The decision must consider an organization's requirements, evaluation criteria, and architecture principles.

94 - How to develop a cloud migration strategy?

Implementing cloud or migration to cloud is challenging. Organizations that have built thousands of applications over the past two to three decades require re-architecting to run efficiently, securely, and resiliently in the cloud. Your next steps are to perform a cloud migration assessment based on your cloud strategy and business objectives. It will help identify the right migration pattern and cloud architecture required to go for the workload. Today we will talk about three vital areas Cloud migration scenario / strategies Cloud migration approach - Take a Workload-centric Approach Cloud migration assessment method You could have different business goals to introduce digital products and services to market faster. You want to reduce your technical debt or replace on-premises infrastructure due to the end of life. All these reasons are leading you to migrate to the cloud. However, you need to decide and call which application/system is the right candidate for cloud migration. You need to have a clear understanding of the target application's only requirements and dependencies. On the other hand, digital transformation forces you to make quick decisions, like Microsoft CEO's famous quote. “We’ve seen two years of digital transformation in two months.” By Microsoft CEO Satya Nadella   References: Session no 91: Workload Migration to Cloud – Getting Started 2 years of digital transformation in 2 months IDC expects 2021 to be the year of multi-cloud as global COVID-19 pandemic reaffirms critical need for business agility Infrastructure and security challenges threaten multi-cloud and edge deployments, new survey from Volterra shows How CIOs and CTOs can accelerate digital transformations through cloud platforms

Workload migration to Cloud has become integral to IT optimization and driving business forward with the increased espousal of cloud technologies. Moving to the cloud enables firms to be more agile, remove inefficiencies and provide required customer, employee experiences. Migration of on-premise enterprise workload to the public cloud has reached the situation of being considered a ‘best practice’. These workload migrations still giving challenges to the traditionally run IT organizations as everything on-premises. It’s no longer moving to the cloud is just selecting your favorite cloud provider, and then magic will be reviled. You and your organization have to face the challenge of making the right choices: Which enterprise workload needs to be migrated to the cloud? What skills required to run the cloud? How will you build a team today & in the future? What services will be available when businesses need them? Some critical factors have to be kept aligned or on top of the list when deciding on the architecture. I will mention what points I keep in mind while suggesting an architecture of enterprise workload migration.

How to deploy a server/instance on the newly released Arm Ampere AI compute shape in Oracle OCI. In this session, we will summarize what we have learned from the last seven sessions on the basics of OCI and you will see how those basics concepts are helping us create a new virtual machine. Two days back, Oracle has announced the release of Arm Based computing on the OCI; with this, Oracle Cloud Infrastructure (OCI) offers Ampere Altra processors with an 80-core Arm server. The Arm is at the ‘heart’ of mobile gaming, and the Arm architecture belongs to ‘reduced instruction set computing (RISC)’ architectures for computer processors. Some of the critical features of this architecture are to provide predictable performance, high scalability, and power efficiency. ARM makes 32-bit and 64-bit RISC multi-core processors. RISC processors are designed to perform a smaller number of types of computer instructions so that they can operate at a higher speed, performing more millions of instructions per second (MIPS).  By stripping out unneeded instructions and optimizing pathways, RISC processors provide outstanding performance at a fraction of the power demand of CISC (complex instruction set computing) devices. I have seen another article written on how to deploy Minecraft on the Cloud. So these two things coincided, and I thought, let me try and create my own Minecraft server on the Oracle Cloud Infrastructure to run an Arm-based workload. All the steps are recorded in the video below, and it took me just twenty minutes to complete the entire process. I am looking forward to deploying enterprise workload to Arm-based instances.

In this session, you will get the three networking choices, which will give you a basic understanding and clarity on the different components and how you can choose each of them while designing it.. Before you go to today’s topic, I want to share with you the mindset of a ‘lifelong learner.’ Lifelong learning is the “ongoing, voluntary, and self-motivated” pursuit of knowledge for personal or professional reasons. Therefore, it enhances social inclusion, active citizenship, personal development, self-sustainability, and competitiveness, and employability. So you can summarize the “self-started education focuses on personal development is a lifelong learning.”
