94 - How to develop a cloud migration strategy?
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.

93 - Cloud Migration Workload Assessment
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.

Tech Talk on Cloud Security Posture Management with John Grange
Detecting and preventing the misconfigurations and threats that lead to data breaches and compliance violations in your multi-cloud environments. For organizations embarking on a multi-cloud strategy, cloud security posture management (CSPM) helps them secure multiple cloud infrastructure as a service (IaaS) providers.

Workload Migration to Cloud - Getting Started
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.

89-Oracle OCI – VNICs, Private, Public IP addresses & DNS, DHCP options – Part 7
In this session part 7, we will cover three topics:
How to manage the virtual network interface cards (VNICs) in a virtual cloud network (VCN). How your instances are assigned private and public IP addresses, and the use of DNS within your cloud network. How to manage the Dynamic Host Configuration Protocol (DHCP) options in a virtual cloud network (VCN).
The Journey started from the first station of networking to learn the basics of Oracle Cloud Infrastructure.
In the second station of our journey to learn Oracle Cloud Infrastructure (OCI). We will cover different gateways available in the VCN like:
Network address translation (NAT Gateway), Service Gateway, Internet Gateway, Dynamic Routing Gateway (DRG), Local Peering Gateway (LPG), and Remote Peering Gateway (RPG).
When you will arrive at the third station of our journey, to learn OCI, you will get the basics of default components of VCN, including the below three-component comes by default with the Virtual Cloud Network on OCI.
Default route table, with no route rules Default security list, with default security rules A default set of DHCP options, with default values
In the fourth station of our journey, we will cover the three different scenarios, public subnet, Private Subnet with a VPN, and Public and Private Subnets with a VPN.
In the fifth and sixth station of the journey to learn the basics of OC we have covered below areas:
Access controls Security Rules Network security groups Security Lists VCN Flow logs
