Module 2 Flashcards
Describe the benefits of high availability
elimination of single points of failure to enable applications to continue to operate even if one of the IT components it depends on, such as a server, fails.
Describe the benefits of scalability
- refers to the ability to adjust resources to meet demand. If you suddenly experience peak traffic and your systems are overwhelmed, the ability to scale means you can add more resources to better handle the increased demand.
-The other benefit of scalability is that you aren’t overpaying for services. Because the cloud is a consumption-based model, you only pay for what you use. If demand drops off, you can reduce your resources and thereby reduce your costs.
two variables of scaling
Scaling generally comes in two varieties: vertical and horizontal. Vertical scaling is focused on increasing or decreasing the capabilities of resources. Horizontal scaling is adding or subtracting the number of resources.
Describe the benefits of reliabilit in the cloud
tw: recover, resources
- ability of a system to recover from failures and continue to function. It’s also one of the pillars of the Microsoft Azure Well-Architected Framework.
- With a decentralized design, the cloud enables you to have resources deployed in regions around the world. With this global scale, even if one region has a catastrophic event other regions are still up and running.
- can design your applications to automatically take advantage of this increased reliability. In some cases, your cloud environment itself will automatically shift to a different region for you, with no action needed on your part.
Describe the benefits of performance predictability in the cloud
-performance predictability focuses on predicting the resources needed to deliver a positive experience for your customers. Autoscaling, load balancing, and high availability are just some of the cloud concepts that support performance predictability
describe the benefits of cost predictability
Cost predictability is focused on predicting or forecasting the cost of the cloud spend. With the cloud, you can track your resource use in real time, monitor resources to ensure that you’re using them in the most efficient way, and apply data analytics to find patterns and trends that help better plan resource deployments.
Describe the benefits of goverance in the cloud
-Things like set templates help ensure that all your deployed resources meet corporate standards and government regulatory requirements.
-can update all your deployed resources to new standards as standards change. Cloud-based auditing helps flag any resource that’s out of compliance with your corporate standards and provides mitigation strategies.
-Depending on your operating model, software patches and updates may also automatically be
- By establishing a good governance footprint early, you can keep your cloud footprint updated, secure, and well managed
-
Describe the benefits of security in the cloud
-Infrastructure as a service provides you with physical resources but lets you manage the operating systems and installed software, including patches and maintenance. If you want patches and maintenance taken care of automatically, platform as a service or software as a service deployments may be the best cloud strategies for you.
-And because the cloud is intended as an over-the-internet delivery of IT resources, cloud providers are typically well suited to handle things like distributed denial of service (DDoS) attacks, making your network more robust and secure.
Describe the benefits of manageability in the cloud (in)
wcap
Management in the cloud speaks to how you’re able to manage your cloud environment and resources. You can manage these:
Through a web portal.
Using a command line interface.
Using APIs.
Using PowerShell.
Describe the benefits of manageability in the cloud (of) (4)
Management of the cloud speaks to managing your cloud resources. In the cloud, you can:
1.Automatically scale resource deployment based on need.
2.Deploy resources based on a preconfigured template, removing the need for manual configuration.
3.Monitor the health of resources and automatically replace failing resources.
4.Receive automatic alerts based on configured metrics, so you’re aware of performance in real time.
Describe Infrastructure as a Service and role in shared responsibility model
- most flexible category of cloud services, as it provides you the maximum amount of control for your cloud resources.
- In an IaaS model, the cloud provider is responsible for maintaining the hardware, network connectivity (to the internet), and physical security.
- You’re responsible for everything else: operating system installation, configuration, and maintenance; network configuration; database and storage configuration; and so on. With IaaS, you’re essentially renting the hardware in a cloud datacenter, but what you do with that hardware is up to you.
Describe platform as a Service and role in shared responsibility model
-Platform as a service (PaaS) is a middle ground between renting space in a datacenter (infrastructure as a service) and paying for a complete and deployed solution (software as a service).
- the cloud provider maintains the physical infrastructure, physical security, and connection to the internet.
- They also maintain the operating systems, middleware, development tools, and business intelligence services that make up a cloud solution. In a PaaS scenario, you don’t have to worry about the licensing or patching for operating systems and databases.
- PaaS splits the responsibility between you and the cloud provider
PaaS is well suited to provide a complete development environment without the headache of maintaining all the development infrastructure.
Describe software as a Service and role in shared responsibility model
Software as a service (SaaS) is the most complete cloud service model from a product perspective. With SaaS, you’re essentially renting or using a fully developed application. Email, financial software, messaging applications, and connectivity software are all common examples of a SaaS implementation.
While the SaaS model may be the least flexible, it’s also the easiest to get up and running. It requires the least amount of technical knowledge or expertise to fully employ.
-SaaS is the model that places the most responsibility with the cloud provider and the least responsibility with the user. In a SaaS environment you’re responsible for the data that you put into the system, the devices that you allow to connect to the system, and the users that have access. Nearly everything else falls to the cloud provider. T
