What is Prometheus, Grafana, and How to learn Online?

by narayan kPrometheusLeave a Comment on What is Prometheus, Grafana, and How to learn Online?

Prometheus is an open-source system monitoring and alerting toolkit originally built at SoundCloud. Many companies and organizations have adopted Prometheus and have a very active developer and user community in the project. It is now a standalone open-source project and is maintained independently of any company.

Features of Prometheus:

  • A multi-dimensional data model with time series data identified by metric name and key/value pairs.
  • PromQL, a flexible query language to leverage this dimensionality.
  • No reliance on distributed storage; single server nodes are autonomous.
  • Time series collection happens via a pull model over HTTP.

What is Grafana?

Grafana is an open-source solution for running data analytics, understanding large amounts of data, and monitoring our apps with the help of cool customizable dashboards.

What are the benefits of Grafana?

  • Customizable dashboards are feature-rich and can be configured to display data from a wide range of databases using visualization tools such as heatmaps, histograms, and charts.
  • The platform is flexible and easy to use.
  • Native support of a broad range of databases.

Grafana Features:

  • Dashboard templating – This is a Grafana feature that is really useful. It allows users to create a dashboard setup to suit their every need.
  • Provisioning – It can be simple enough to set up a single dashboard with a few clicks, dragging and dropping, but some users need even more ingenuity this way.
  • Annotations – This Grafana feature lets you mark graphs, which is especially helpful when you need to correlate data in case something misbehaves.
  • Custom plugins – You can extend the functionality of Grafana with plugins that provide additional tools, visualizations, and more.
  • Teams and permissions – Where an organization has an instance of Grafana and multiple teams, they usually prefer to have the option of implementing some dashboard isolation.

Pre-requisites to learn Prometheus and Grafana:

  • Basic experience with Linux/Unix system administration.
  • Familiarity with common shell commands, such as ls, cd, curl, etc.
  • Some knowledge and/or development experience in Go and Python.
  • Some experience working with Kubernetes.

What is the future of AWS Solution Architect Associate?

by Manish KumarAmazon Web ServicesLeave a Comment on What is the future of AWS Solution Architect Associate?

In this particular blog, we will take a look at the future of AWS Solution Architect Associate and also rising demand for AWS Solution Architect Associate Jobs. Cloud computing become a lot of and a lot of well-known, a lot of and a lot of businesses and organizations area unit getting down to move to the AWS platform. These days numerous businesses and organizations area unit moving their services and apps on AWS platform. AWS includes a hundred seventy five services starting from networking and storage to advanced AI and IoT tools. And that’s simply at the high level. Once you get into the AWS services, there’s a fair deeper level of selection.

To understand that AWS services and merchandise to use is simply as necessary an ability on the way to use them. That’s the role of the AWS Solutions creator.

What is an AWS Solutions Architect?

AWS solutions architect are the ones for set up security, storage, and networking. These skill of a solutions architect to pick the proper AWS services is incredibly valuable, and the best way to validate that skill is with the AWS Certified Solutions Architect – Associate certification.

Professionals out there who want to become an AWS Solutions Architect certification only need to pass SAA-C02 exam.

The exam is not easy and about of 130-minute, consist of multiple-choice exam, and it costs $150. The AWS Solutions Architect – Associate certification requires both deep AWS product knowledge as well as how all the services interact. That’s very much reflected in the exam objectives:

  • Design resilient architectures
  • Design high-performing architectures
  • Design secure applications and architectures
  • Design cost-optimized architectures

How difficult is the AWS Solutions Architect?

The AWS Solutions Architect – Associate is an entry-level certification by AWS.  This certification is designed to validate the expertise that learn as an architect, which isn’t an entry-level job. The task of a solutions architect is to find a balance between the competing forces of technology and business needs. When designing architectures, solutions architects need to balance security, performance, resilience, and cost as well as customer requirements.

Solutions architects need to know which instance to use and when. Now expand that knowledge base to the entire panoply of AWS services. It’s a lot. Now consider the type of question you may see on the AWS Solutions Architect – Associate exam.  AWS certification exams aren’t necessarily known for curveball exam questions, but pay careful attention to the details. That’s what makes this particular test more difficult than others.

Designing secure, resilient, high-performance, cost-effective architectures isn’t easy — and the exam reflects the balancing act. Don’t let this Associate-level certification fool you. It’s a tough exam, but it’s doable.

AWS Solutions Architect Associate Salary

Unsurprisingly, you don’t truly see the duty title “AWS Solutions Architect” on the duty boards too usually (unless you’re observing Amazon jobs). Instead, you’ll usually see job titles like cloud creator, systems creator, or cloud solutions creator. These generic creator positions are usually expert-level roles that need a minimum of a number of years of creator expertise — further as associate degree creator certification.  The level of experience is actually mirrored within the wage. The typical wage for a cloud creator in urban center is $118,736. Meanwhile, cloud creator positions in Cleveland, Ohio, solely pay $98,486 p.a. The national average for a cloud creator is around $105,000 p.a. It’s vital to notice that you just will earn the AWS Solutions creator – Associate certification and still be under-qualified for many cloud creator positions.

Bear in mind that Associate-level AWS certifications are still thought of entry-level. To completely notice your earning potential and land employment as a cloud creator, you’ll would like a minimum of 5 or six years of expertise additionally to the certification.

Is the AWS Solutions Architect Worth It?

If you’re working at a company that uses AWS, the AWS Solutions Architect – Associate certification is absolutely worth it. However, it depends on what you want to do with it.  For someone with a few years of AWS experience, then the Solutions Architect certification can help validate the skills you need to move into a higher-level engineer or entry-level architect role.  Again, the Solutions Architect certification alone won’t get you an architect job, but it’ll position you well enough to make the jump once you have the experience. To earn that title, you’ll need to spend a few years working with stakeholders to develop secure, scalable, resilient AWS architectures. Once you’re there, you can look back and see the cert was definitely worth it.

I hope this particular blog is helpful and informative for you, If you want to know more about AWS and want to learn AWS and become a AWS Certified professionals then I would like to suggest you DevOpsSchool.com, one of the top institute for AWS Certified Architect Associate in top cities like Hyderabad, Bangalore and Globally.

Thank You!!

What is the difference between Azure and AWS?

by Manish KumarAmazon Web Services / azureLeave a Comment on What is the difference between Azure and AWS?

Amazon Web Services (AWS) and Microsoft Azure are two of the biggest names in public cloud computing. For example, if an organization is in need of a strong Platform-as-a-service (PaaS) provider or needs Windows integration, Azure would be the preferable choice while if an enterprise is looking for infrastructure-as-a-service (IaaS ) or diverse set of tools then AWS might be the best solution.

In this particular blog we will going to discuss about the differences between AWS and Azure, taking a look on various aspect, and then we see for better choice?

What is Azure?

Azureis the primary interface for managing apps, services and solutions commissioned on the Azure platform. This feature-rich web application allows you to interact with Azure services through a rich web-based interface, building, managing, and monitoring everything from simple web apps to complex cloud applications in a single, unified console.

Advantages of Azure

Here are some advantages of adopting Azure cloud services:

  • Capability for developers and users to create, maintain and deploy applications
  • Fully scalable cloud computing platform offers open access across multiple languages, frameworks, and tools
  • Total support for Microsoft legacy apps
  • Support for mixed Linux/Windows environments
  • Offers inbuilt tool like Azure stack to help the organization deliver Azure service from the own data centre.

What is AWS?

Amazon Web Services (AWS) is a secure cloud services platform, offering compute power, database storage, content delivery and other functionality to help businesses scale and grow. It is a subsidiary of Amazon providing on-demand cloud computing platforms.

Advantages of Azure

Here are some advantages of AWS cloud services:

  • Compute Cloud allows you to increase or decrease storage according to the need of your organization
  • AWS enables you to select an operating system, programming language, database of your choice
  • Robust partner ecosystem
  • Broad & deep service offerings
  • High Transfer Stability
  • Offers more data centres for availability and low latency
  • Stronger support for Bl and analytics
  • Better DevOps support

EcosystemAWS has a software marketplace with an extensive partner ecosystem.With very few Linux options, Azure doesn’t’ have a big ecosystem.
Support for Big DataEBS storage is ideal for handling big data.Standard storage has many issues for big data, and therefore you need premium storage.
MaturityMore mature cloud environment for big data.The less mature environment for big data.
Machine accessIn AWS machine can be accessed separately.Machines are grouped into cloud service and respond to the same domain name with various ports.
SalaryThe average salary for “AWD engineer” is approximately $141,757 per year for Software Architect.The average salary for “Microsoft Azure” ranges from approximately $113,582 per year.
Key featuresZero setups, Detail Monitoring, Auto-scaling groups.Start-up friendly, High performance, Low cost.
Long term data archivingAllows long term data archiving and retrieval.Does not offer any long term data archiving and retrieval option.
SecuritySecurity is provided using defined roles with permission control feature.Provides security by offering permissions on the whole account.

Conclusion

Comparing Azure and AWS is extremely difficult as both continue to launch new pricing structures, new products, and new integrations. Microsoft Azure has increased its market share in the last couple of years, but not to an extent where there is a real contest between the two companies at least for the near future.

 The decision to choose either of the platforms depends on the needs of organizations how AWS vs Azure comparison meets those requirements.

 Therefore, the final selection will be depend on the need of your organization.

I hope this particular blog is helpful and informative about AWS and Azure, If you want to learn AWS and Azure, then I would like to suggest you DevOpsSchool.com, one of the top institute for AWS and Azure Certification both online and offline mode in top cities like Hyderabad, Bangalore and Globally too.
