Amazon Personalize and Amazon OpenSearch Service Integration

‍

When you use Amazon Personalize with Amazon OpenSearch Service, Amazon Personalize re-ranks OpenSearch Service results based on a user's past behavior, any metadata about the items, and any metadata about the user. OpenSearch Service then incorporates the re-ranking before returning the search response to your application. You control how much weight OpenSearch Service gives the ranking from Amazon Personalize when applying it to OpenSearch Service results.

With this re-ranking, results can be more engaging and relevant to a user's interests. This can lead to an increase in the click-through rate and conversion rate for your application. For example, you might have an ecommerce application that sells cars. If your user enters a query for Toyota cars and you don't personalize results, OpenSearch Service would return a list of cars made by Toyota based on keywords in your data. This list would be ranked in the same order for all users. However, if you were to use Amazon Personalize, OpenSearch Service would re-rank these cars in order of relevance for the specific user based on their behavior so that the car that the user is most likely to click is ranked first.

When you personalize OpenSearch Service results, you control how much weight (emphasis) OpenSearch Service gives the ranking from Amazon Personalize to deliver the most relevant results. For instance, if a user searches for a specific type of car from a specific year (such as a 2008 Toyota Prius), you might want to put more emphasis on the original ranking from OpenSearch Service than from Personalize. However, for more generic queries that result in a wide range of results (such as a search for all Toyota vehicles), you might put a high emphasis on personalization. This way, the cars at the top of the list are more relevant to the particular user.

‍

Irrespective of your business size, you can’t ignore the value assessment of any product or service you plan to purchase. The right investment in the right system, process, and infrastructure is essential for success in your business. And how can you make the right financial decisions and understand whether “X” product/service is generating value or not for your business?

Total Cost of Ownership or TCO analysis is one method that can help you in this situation, especially if you are planning to analyze these costs on the cloud. Amazon’s AWS is a leading public cloud platform offering over 200 fully featured services, including AWS TCO analysis -a service to analyze the total costs of an asset or infrastructure on the cloud. It offers services to diverse customers – startups, government agencies, and the largest enterprises. Its agility, innovation, safety, and several data centers make it comprehensive and adaptable.

Read on to learn more about the TCO analysis and how AWS TCO analysis works.

What is TCO analysis?

As the name suggests, TCO estimates costs associated with purchasing, deploying, operating, and maintaining any asset. The asset could be physical or virtual products, services, or tools. The TCO analysis’s primary purpose is to assess the asset’s cost throughout its life cycle and to determine the return on investment.

Regarding the IT industry, TCO analysis consists of costs related to hardware/software acquisition, end-user expenses, training, network, servers, and communications. According to Gartner, “TCO is a comprehensive assessment of IT or other costs across enterprise boundaries over time.”

TCO analysis in Cloud

The adoption of cloud computing in business also raises the trend of TCO analysis on the cloud. You can call it, cloud TCO analysis, which performs the same job on the cloud. TCO analysis in the cloud calculated the total costs of adopting, executing, and provisioning cloud infrastructure. When you are planning to migrate to the cloud, this analysis helps you to weigh the current costs and cloud adoption costs. Not only Amazon, but other big tech giants, including Microsoft, Google, IBM, and many more, offering TCO analysis in the cloud. But, Amazon’s AWS is the number one cloud service provider to offer cloud services.

Why do businesses need AWS TCO analysis?

A TCO analysis helps to know whether there will be profit or loss.

Let’s understand it with an example showing how AWS TCO analysis helped the company increase its profit. The top OTT platform, Netflix, invested $9.6 million per month in AWS Cost in 2019, which would increase by 2023. According to this resource, it would be around $27.78 million per month. The biggest reason behind this investment is the profit, and AWS TCO analysis is helping them to know how this profit is happening. AWS helped Netflix to get a cost-effective and scalable cloud architecture horizontally. It also enabled the company to focus on its core business – video streaming services. You all know that Netflix is the favorite video streaming platform globally.

In another example, delaying the decision of TCO analysis ignorance resulted in a loss. According to this report on 5GC, TCO analysis has been done regarding the adoption of the 5G core. It has been found that postponing increases the TCO over five years. It indicates the losses occurred due to ignorance of TCO analysis.

These examples show that your business needs both TCO analysis and cloud infrastructure. A lack of TCO analysis might cause incorrect IT budget calculations or purchasing of inappropriate resources. It might result in problems like downtime and slower business operations. You can understand that the TCO analysis is a critical business operation. Its ignorance directly impacts financial decisions. Thus, know this and utilize AWS TCO analysis for your business success.

How does AWS TCO Analysis work?

AWS TCO analysis refers to calculating the direct and indirect costs associated with migrating, hosting, running, and maintaining IT infrastructure on the AWS cloud. It assesses all the costs of using AWS resources and compares the outcome to the TCO of an alternative cloud or on-premises platform.

AWS TCO Analysis is not a calculation of one resource or a one-step process. To understand how it works, you need to know the costs of your current IT infrastructure, understand cost factors, and how to optimize cloud costs when you deploy and manage scalable web applications or infrastructure hosted on-premises versus when you deploy them on the cloud.

Here are steps to help you understand how AWS TCO analysis works:

Preliminary steps – Know the current value and build a strategy

Step 1 – Evaluate your existing infrastructure/ web application cost

You must calculate and analyze the direct and indirect costs of your existing on-premise IT infrastructure. Perform the TCO analysis of this infrastructure, including various components.

• Physical & virtual servers: They are the main pillars in developing the infrastructure
• Storage mediums: Cost of database, disks, or other storage devices
• Software & Applications: The analysis finds the cost of software and its constant upgrades. It also estimates the costs of acquiring licenses, subscriptions, loyalties, and vendor fees
• Data centers: The analysis needs to check the costs of all linked equipment such as physical space, power, cooking, and racks with the data centers
• Human Capital: Trainers, consultants, and people who run setups.
• Networking & Security system: Find out the costs of these critical components

Don’t limit yourself to estimating only direct/indirect costs. Find out any hidden costs that might happen due to unplanned events like downtime and opportunity costs, which might be helpful in the future.

Step 2 – Build an appropriate cloud migration strategy

You must choose an appropriate AWS cloud migration strategy before calculating monthly AWS costs. Amazon offers many TCO analysis migration tools, such as CloudChomp CC Analyzer, Cloudamize, Migration Evaluators, etc., from AWS and AWS partners. It can help you to evaluate the existing environment, determine workloads, and plan the AWS migration. It provides excellent insights regarding the costs, which can help you to make quick and effective decisions for migration to AWS.

Primary step – Estimate AWS Cost

Know these cost factors

All industries have different objectives and business operations. Thus, their cost analysis differs according to AWS services, workloads, servers, or methods of purchasing other AWS resources., the cost depends on the working usage of services and resources.

Still, you must consider the following factors directly impacting your AWS costs.

• Services you utilize: AWS offers various computing services, resources, and instances with hourly charges. It will bill you from when you launch any resource/instance until termination. You will get other options to use predetermined set costs for making reservations.
• Data Transfer: AWS charges for aggregated outbound data transfer across services according to a set rate. AWS does not charge for inbound or inter-service data transfer within a specific region. Still, you must check data transfer costs before launching.
• Storage: AWS charges for each GB of data storage. As per consumed storage classes, you need to understand the cost analysis. Remember that cold and hot storage options are available, but hot storage is expensive and accessible.
• Resource consumption model: You get options to consume resources. Such as on-demand instances, reserved instances that give discounted prepay options for on-demand instances, and AWS saving plans.

Know how to use AWS Pricing Calculator

Once you analyze your compute resources and infrastructure to deploy, understand these factors, and decide on necessary AWS resources, you need to use AWS Pricing Calculator for expected cost estimation. This tool helps determine the total ownership cost. It is a web service that is freely available to end-users. It permits you to explore services according to need and estimate costs.

These reasons would help you to know the rising demands of cloud-based disaster recovery strategies among business industries.

Develop a Disaster Recovery Plan (DRP)

Implementation of any strategy requires a plan and checklist. You must also make a disaster recovery plan and tick mark the essential checklist to implement any cloud-based disaster cloud strategy. Generally, this plan must be part of a Business Continuity Plan (BCP), which ensures business continuity during and after disasters.

The following 3 tasks will make things easy for you regarding adopting the cloud-based DRP.

Task 1: Know your infrastructure

Your first job is to understand your existing IT environment and assess the data, assets, and other resources. You must know everything, like where data has been stored, the cost of these data, and possible risks. Evaluation of the risks and threats can help you understand the possible types of disasters that might happen.

Task 2: Conduct a business impact analysis and risk assessment

Your next job is to do business impact analysis to measure the business impacts of disruptions to your workloads. Simply put, find out the business operations constraints once disaster strikes. Additionally, do a risk assessment to learn the possibility of disaster occurrence and its geographical impact by understanding the technical infrastructure of the workloads. Don’t forget to consider these two essential factors:

• Recovery Time Objective (RTO) – It refers to the maximum time (acceptable delay), an application can stay offline after the disaster to its recovery.
• Recovery Point Objective (RPO) – It refers to the maximum time (adequate time) for which you can bear data loss from your application. In other words, find the lost time between service interruption and the last recovery point.

Look at the below image to understand these factors more easily:

Task 3: Know your workloads to implement disaster recovery in the cloud

Implementing disaster recovery on on-premise is different from implementing it in the cloud. To execute cloud-based disaster recovery effectively, you need to analyze your workloads. You must check your data centre connectivity if you have already deployed the workload on the cloud.

But, deploying your workloads on the AWS cloud would benefit disaster recovery implementation. AWS will take of everything from data center connectivity to providing fault-isolated Availability Zones ( an area to support physical redundancy), and regions.

• Go for a single AWS Region if you have high workloads, as you will get different availability zones.
• Go for multiple AWS Regions if there is a possibility of losing various data centers far from each other.

Disaster recovery strategy options in AWS Cloud

The rising popularity of AWS is happening because of more than 20 AWS services available for disaster recovery. But every business has its objective, background, and technical infrastructure. Thus, you should know all options. AWS Cloud offers four major approaches for disaster recovery, shown in the following image:

Image: Disaster Recovery Approaches

Let’s understand each approach and all available AWS services within each approach.

(1) Backup & Restore

Backup & Restore is a common approach for disaster recovery. Check the following table to learn more about it:

What it does

• Mitigate data loss and corrupted data
• Replicate data to AWS regions
• Mitigate lack of redundancy for workload deployed to a single Availability Zone

What you need to consider

• Use Infrastructure as code (IaC) for deployment, and for this, consider AWS CloudFormation or AWS Cloud Development Kit.
• Develop a Backup strategy using AWS Backup
• Create Amazon Ec2 instances using Amazon Machine Images
• Automate redeployment using AWS CodePipeline

Available AWS Services

• Amazon Elastic Block Store (Amazon EBS) Snapshot
• Amazon DynomoDB backup
• Amazon RDS snapshot
• Amazon EFS backup
• Amazon Redshift snapshot
• Amazon Neptune snapshot
• Amazon DocumentDB

Check the following image to understand the backup and restore architecture on the AWS cloud.

(2) Pilot Light

Pilot light is a second approach for disaster recovery through replication (continuous, cross-region, asynchronous). Check the following table to learn more about it:

What it does

• Helps you to replicate data from one Region to another region
• Allows you to work on your core infrastructure and quickly provision a full-scale production environment through scaling servers and switching on

What you need to consider

• Automate IaC and deployments to deploy core infrastructure at one place and across multiple accounts and Regions
• Use different accounts per Region to offer the highest level of security isolation and resources

Available AWS Services

• Amazon Simple Storage Service (S3) Replication
• Amazon Aurora global database
• Amazon RDS read replicas
• Amazon DynamoDB global tables
• Amazon DocumentDB global clusters
• Global Datastore for Amazon ElastiCache for Redis
• AWS Elastic Disaster Recovery
• For Traffic Management
• Amazon Route 53
• AWS Global Accelerator

Check the following image to understand the Pilot Light architecture on the AWS cloud.

(3) Warm Standby

The warm Standby approach focuses on scaling. Check the following table to learn more about it:

What it does

• Ensure the scaling and fully functional copy of the production environment in another Region
• Offers quick and continuous testing

What you need to consider

• Scaleup everything which needs to be deployed and running
• Since it is similar to the Pilot Light approach, consider factors, RTO & RPO for selecting one from these.

Available AWS Services

• You can use all AWS services mentioned in the above two approaches for data backup, data replication, infrastructure deployment, and traffic management.
• Use AWS Auto Scaling for scaling resources

Check the following image to understand the Warm Standby architecture on the AWS cloud.

(4) Multi-site active/active

Multi-site active/active approach offers disaster recovery in multiple regions. Check the following table to learn more about it:

What it does

• Helps you to recover data in various regions
• Reduce recovery time but also offer a complex and expensive approach

What you need to consider

• Don’t forget to test the disaster recovery to know how the workload responds to the loss of a Region
• You need to work more on maintaining security and avoiding human errors

Available AWS Services

• Like Warmup Standby, you can use all AWS services mentioned in the above three approaches for data backup, data replication, infrastructure deployment, and traffic management.

How to choose a suitable strategy

It would be best if you made the right decision by selecting the appropriate strategy according to the business requirements. Still, consider the following points and check to decide the best one:

Points to consider

• AWS divides services into two categories – the data plane to offer real-time services and the control plane to configure the environment. It is suggested that you should go with data plane services to get maximum resiliency.
• Choose the Backup & Restore strategy options if you need only backup of workloads and restorage with the single physical data center. Besides this requirement, you can choose from rest 3 strategies.
• The first 3 approaches are active/passive strategies which use an active site like AWS Region for hosting and serving and a passive site (another AWS Region) for recovery.
• Regular testing and updating of your disaster recovery strategies are vital. You can take the help of AWS Resilience Hub to track your AWS workload.
• Use AWS Health Dashboard to get up-to-date information about the AWS service status. It provides a summary like the below image:

Tick-make this checklist for your DRP and strategies implementation

Here is a checklist that can help you to effectively design, develop, and implement disaster recovery plans and strategies. Consider it like a questionnaire for successful implementation:

Have you figured out recovery objective (RTO / RPO)?Have to found the stakeholder lists which needs to update once disaster strike?Have you established the essential communication channels during and after disaster events?Have you collected all business operations and IT infrastructure documents?Have you defined any procedure to manage incidents or actions?Have you performed testing of your strategies? Use AWS Config for monitoring the configurations.Does your documentation are up-to-date?

Case study – How Thomson Reuters got benefits after implementing AWS cloud-based disaster recovery approach

In 2020, Thomson Reuter, a Global news and information provider, depended on the traditional Disaster recovery process, which was time-consuming and expensive. The company realized the need for modern cloud-based disaster recovery to improve data security and recover applications for one of its business units. They connected with Amazon AWS and AWS partner Capgemini and decided to implement AWS Elastic Disaster Recovery to minimize data loss, downtime, fast recovery, and on-premises recovery. In 10 months, the company implemented this strategy on 300 servers. The automation of the cloud-based DR process provided them with the following outcomes:

• Replicated over 120 TB of data from 300 servers
• Setup a recovery site in the cloud
• Eliminate its manual DR process
• Optimized spending on its DR process
• Enhanced security and data protection

See the below image to understand how AWS Elastic Disaster Recovery works. It is visible that it follows the simple process of recovering and replicating any data. In this case, the company also leveraged this work, but before that, they built an AWS Landing Zone to set up a secure and multi-account AWS environment to meet the security requirements. Afterward, they set up a recovery site in the cloud using the AWS Elastic Disaster Recovery service. This new solution has started offering continuous data replication at minimum costs.

Executive Summary

Continuing the development of a musician networking platform which involved implementing new features, enhancing the existing ones, and fixing bugs/errors/issues in the platform by improving its efficiency and productivity along with making the platform responsive.

Problem Statement

Our client wanted us to design and create a social platform where each and every user is able to connect and interact with one another easily. He came to us after a bad experience with some other company and was expecting to continue the development by improving website performance as well as efficiency.
The platform had various bugs which needed to be fixed and some major features were to be added like payment service, OTP service, adding more security along with improving existing features. Performance of platform was being affected as there were some major issues like:
1. Deployment architecture- Everything was deployed on a single EC2 instance due to which there was a high amount of downtime. The performance was impacted more when the user base was increased.
2. The videos on his platform were taking a lot of time to load.

Our Solutions

1) We followed MVC architecture for developing REST API using express as middleware and mongoose for managing data in MongoDB. Authenticated API with jwt by using JSON web token package.
2) Added payment service in the platform by integrating stripe payment gateway with help of stripe package, created OTPs for security/validation which was communicated via SMS with help of Twilio.
3) To improve the performance, we deployed the backend on a separate ec2 instance with Nginx as reverse proxy and pm2 as process manager which comes with a built-in load balancer and helps to keep the application alive forever.
4) Installed Nginx on the server, and changed the Nginx.conf file configurations as per the requirement and it worked as a load balancing solution. Also replaced the lets encrypt SSL certificates with ACM(AWS Certificate Manager) to make certificate renewal, provision, and management process better as well as easy.
5) For adding new features to the platform, the frontend involved creating several components, services, directives, pipes, and modules in Angular.
6) To reduce the load time we implemented Lazy loading with help of Lazy load routes. The reason behind increased load time for videos was the use of video tag over secured protocol, to solve this we used iframe for rendering videos which proved to be much faster.
7) Changed the existing deployment architecture and moved the front-end to S3 so that load on the server can be reduced. We moved the front-end to S3 with CloudFront as CDN for speeding up the distribution of web content and improving performance.

Technologies

Angular 10, Node, Express, MongoDB, AWS S3, EC2, CloudFront

Success Metrics

1. Provided all the deliverables within the expected deadlines, improved performance as down time reduced and videos were no longer buffering for a long time.
2. Met all the expectations of the client and with positive feedback. All his meetings with directors and students were successful due to which he wanted us to implement some more new features on his platform.
3. Continuous reporting of progress to the client.
