Cloud Infrastructure
The hardware and software components that enable cloud computing, including computer hardware, networks, and the software abstraction layer.
Cloud Environment
The combination of cloud infrastructure and tenants or customers utilizing the cloud services.
Cloud Abstraction Layer
A software layer deployed on computer hardware to create the essential characteristics of cloud computing.
Virtualization
A key component of cloud computing where servers and storage are virtualized to create virtual machines.
Elastic Load Balancing
A virtual network device in the cloud that helps distribute workloads across multiple compute and storage instances.
Amazon Virtual Private Cloud
A networking service that allows the creation of a virtual network in the AWS cloud to provide dedicated resources for an enterprise.
Security Groups
Groups of individuals in the cloud environment with privileged actions on cloud instances, similar to administrators in traditional IT landscapes.
Amazon S3
Amazon's Simple Storage Service, used for batch storage in cloud applications.
Amazon DynamoDB
A non-relational database service provided by Amazon for cloud applications.
Virtual Private Cloud (VPC)
A networking service in AWS that enables the creation of a virtual network for cloud services to operate as if they are on the same network.
Legacy IT
Refers to traditional IT where all IT capabilities are on-premises, including operational and management responsibilities for hardware, software, networking, and storage, all managed by the cloud consumer.
Infrastructure as a Service (IaaS)
In this cloud service model, virtualized capabilities are provisioned in the cloud, with the cloud consumer responsible for installing the operating system and building the software stack on top of it.
Platform as a Service (PaaS)
In this model, the cloud consumer builds and deploys applications that run on the underlying platform, with the consumer responsible for the applications' security while the platform's security is managed by the service provider.
Software as a Service (SaaS)
This cloud service model involves consumers using full-featured software in the cloud, with complete operations and management responsibilities resting with the cloud service provider.
Hybrid Cloud Operating Model
In this model, the IT organization acts as both a provider and a broker, managing services and negotiating deals with public or community cloud providers while stitching together different cloud computing models.
Cloud Drivers
The main driver for moving to the cloud is the potential for increased return on investment due to the pay-as-you-go or subscription model, leading to lower upfront investments and faster payback.
Cloud Security Concerns
Moving to the cloud raises concerns about security control, compliance, and shared computing challenges, including inheriting security vulnerabilities from virtualization and limited control over subscribed services.
Cloud Revenues
Cloud revenues are growing rapidly, with different services like business process services, platform as a service, cloud application services, and infrastructure as a service contributing to the market's significant size and growth.
Cloud First World
Default assumption of moving into the cloud and justifying not doing so.
Workload Identification
Process of identifying applications and processes that benefit most from cloud migration.
Hybrid IT
Utilizing both on-premises and cloud solutions for different applications.
Enterprise ERP Systems
Core business process systems in large companies often not suited for cloud migration due to control and capability concerns.
Private Cloud
Cloud adoption model offering benefits of cloud with lower risk and more control.
Cloud Adoption Framework
Six actions and five perspectives to develop a cloud strategy.
Cloud Migration Framework
Gartner's approach to assess applications for cloud migration based on service and deployment models.
Discovery Process
Initial step in cloud migration involving inventorying all applications in the environment.
Cloud Decision Framework
Tool to choose cloud models, deployment models, and service models based on specific needs and considerations.
Vendor Selection Process
The process of choosing the most suitable vendor for cloud services based on various criteria such as capabilities, pricing, and reliability.
Risk Mitigation
Strategies and actions taken to reduce or eliminate potential risks associated with cloud adoption, ensuring data security and compliance.
Steady State Operations
Refers to the stable and ongoing operational phase after the migration to the cloud, where day-to-day activities are managed efficiently.
Business Alignment
Ensuring that IT initiatives and investments align with the strategic goals and needs of the business to drive value and support growth.
Training and Skill Development
The need for IT organizations to provide training and upskill employees to adapt to the new cloud-based operational model effectively.
Governance
Establishing processes and skills within the IT organization to align with business objectives and ensure effective management of cloud resources.
Security Responsibility
Clarifies that while cloud providers may handle security capabilities, the organization remains liable for any security breaches and associated consequences.
Operations Protocols
Defined procedures and guidelines for the day-to-day interactions between end-users and the IT landscape provisioned in the cloud to ensure smooth operations.
Cloud Myths
Common misconceptions about cloud adoption, such as the belief that cloud is solely about cost savings or that it is always more secure than on-premises solutions.
Multi-Cloud Strategy
The approach of using multiple cloud providers to prevent vendor lock-in and leverage specialized services that a single provider may not offer.
Cloud Deployment Models
Different models such as private, public, community, and hybrid clouds that organizations can adopt.
Hybrid Cloud Model
A cloud model where organizations use a combination of private and public cloud services, leading to significant implications for the IT organization.
Cloud Service Models
Various models like infrastructure as a service, platform as a service, and software as a service that organizations can choose for migrating to the cloud.
Security Challenges in Cloud Computing
Issues like insecure APIs, shared underlying technology vulnerabilities, and lack of visibility into the service provider's operations pose security risks.
Identity and Access Management
Ensuring seamless integration between the cloud provider and the consumer's IAM solution to manage access securely.
Security Operations Center
A robust center within the cloud provider responsible for security assessments, incident management, and response capabilities.
Regulatory Environment
Cloud providers must adhere to security frameworks satisfying regulatory requirements, often requiring third-party audits for validation.
Resiliency and Availability
Cloud providers need to guarantee significant availability defined in contracts, especially for remote locations with unstable network connections.
Change Management Policies
Policies for release, change management, and user-driven change acceptance are crucial, particularly in a platform as a service model.
Enterprise Resource Planning (ERP) in the Cloud
Large companies moving ERP systems to the cloud need defined security zones, data protection, and process-level access provision.
