Take the first step towards transforming your apps into cloud-native
If you are a medium-sized or large organization which depends on your IT teams to provide you with on-demand infrastructure, and support for your business critical applications; if you are an organization with sprawling thousands of applications and are planning to take the journey, or are already on a path, to cloud-native, you must have faced questions like "where do I start in migrating these applications to a new cloud platform?" Or "Once I've migrated an application on to a cloud platform, how do I make sure my application code updates don't drift away from leveraging the most a cloud platform has to offer?".
Let's take a real world example. An organization that has 1500 Applications, about 80% of which are Commercial-Off-The-Shelf (COTS) apps, and about 20% are custom home-grown. These applications are mostly run on unix-based systems, with some instances run on Windows hosts, and they are looking for assistance on getting started with questions like – how do they decide which applications to move? what changes need to be made to these applications to be compatible with the new platform? what risks and vulnerabilities are associated in not taking any actions on these applications? how long will the effort be to migrate these applications? are these applications even ready to be migrated? and so on.
CAST Software provides organizations the ability to have automated application assessments for an entire portfolio of applications using various programming languages, and profile them based on multiple quality and quantity indicators. Using a combination of an assessment questionnaire and the automated code insights, CAST helps you decide which applications to target migrating first, how code changes affect an application resiliency, identify security vulnerabilities in the existing application code, and much more. CAST also provides the ability for you to export the results of your application assessment without the need to export any source code. This can be done by leveraging CAST API. For the example customer mentioned above with thousands of applications, the process of evaluating their entire portfolio of applications can be easily automated leveraging this function.
Here is an example of how the command line API call would look like, that would export the application metrics without the need to export any source code -
java -jar HighlightAutomation.jar --workingDir "/samples/pathToWorkingDir" --sourceDir "/samples/sourceDir/src/" --skipUpload
Since jar files can be run on Unix and Windows systems alike, the command remains the same for both platforms. You can also use the command wrapper created by Keyva (https://github.com/keyva/casthighlight_wrapper) to run the assessment.
For the aforementioned customer, coupling up the ability to run API commands with their configuration management system or a workflow automation system like Red Hat Ansible, they can scan for source code on their server inventory for all on-premises or cloud based servers, and automatically create an application portfolio assessment report on a scheduled basis.
To get started with our application assessment questionnaire, please visit us at https://keyvatech.com/survey/. We also provide a free assessment for one of your applications built using Java or Python and help you roadmap the required effort and the steps you would need to take to assess and migrate your entire portfolio of applications.

This is only exacerbated by the myriad of technology and tools in the market that now exists. How can Operations teams keep up with increasing demand of managing larger and ever-changing workloads under shrinking budgets? That’s a question which many organizational teams are left to answer and find a solution that fits their needs. Are you faced with this challenge? One step that can get your team closer to the solution is to genericize your processes independent of tools, so that teams can follow a unified process and gain end to end visibility in to their entire infrastructure – regardless of the underlying technology that is deployed. Closed-Loop-Incident-Process is one such operational process, that has tremendous benefits when coupled with automation and tools consolidation. A Closed-Loop-Incident-Process A Closed-Loop-Incident-Process, or CLIP for short, is when you automatically take actions on alerts on your Network Operations Center (NOC) unified console including auto remediation, while integrating the remediation process with your ticketing system (e.g. Incident tickets). It does not matter whether you use one of the APM tools, or infrastructure monitoring tools, and the process holds true for any and all IT Services Management (ITSM) and Continuous Management Data Base (CMDB) systems you have. Once your teams agree on an end to end process that works for their environment and organization, you can begin the work of integrating the various tool sets you have to achieve the end goal. [caption id="attachment_1278" align="alignleft" width="212"] Fig 1a.[/caption] It is important to keep your CMDB accurate and current, and many organizations end up spending a lot of cycles and redundant time trying to achieve that state. Eventually, organizations can use the CIs and CI relationships within the CMDB to implement event correlation and operational intelligence that can proactively reduce alerts that would’ve been classified as noise. Check out the CLIP framework here (fig 1a) here. How Kevya Can Help Keyva has helped several customers integrate and automate their operational processes to achieve time and cost savings. Keyva can help genericize the many different processes you may have and integrate tool sets to achieve end to end use case automation, with the end goal of achieving Operational Intelligence so the operations teams can put time towards automating complex remediation tasks, rather than on repetitive manual tasks.

The integration allows users to trigger Ansible jobs from within ServiceNow Catalog Requests or Change tickets. Users have the ability to customize triggers to suit their own needs – to not only launch the Ansible job from a specific ServiceNow Application, but also being able to define the specific conditions (e.g. Status field set to ‘In Progress’). Many organizations use Ansible as the automation and orchestration layer, while using ServiceNow as their ITSM suite and CMDB. There are several common use cases that require an integration between the two offerings. [caption id="attachment_1260" align="alignleft" width="211"] Fig 1a - Sample Provisioning Use Case[/caption] A similar use case can be implemented using this integration for Day 2 tasks like Patching, or Unprovisioning. Customers that are looking to launch a service request through a centralized portal like ServiceNow, and have Ansible as their orchestration fulfillment engine can leverage this open sourced integration. Check out the sample provisioning use case (fig 1a) here.

Data Analysts and Database Managers can follow DevOps practices for managing updates and new database releases across various environments in a uniform fashion, to produce repeatable results. Just like application teams create and manage the CI/CD pipeline for applications, the data that these applications consume can have its own release pipeline that is managed by the database teams. In many cases, cloud based data warehousing platforms provide the ability to host the applications that consume this data, all within the same environment. Applications that consume data housed in a data warehouse may also leverage Kafka or other DevOps tools to achieve low latency query performance. As you release updates to your applications, you may also need to account for the updates to the service bus layer and the database layer. Continuous deployment and continuous integration becomes all the more important. Data teams that institute DevOps practices and tools for data warehousing can promote an agile culture within their silos. This includes the process of fetching or discovering the data for data warehousing, the process of making sure it is current and accurate for the consuming applications, and the process of organizing it for data mining and analysis. You can apply DevOps practices and policies to data automation (just like infrastructure automation). Starting from self-service models to request new data instances, to requesting updates, and other data lifecycle steps. There are many organizations that have built entire data platforms on containers. For infrastructure and database teams, it is imperative to provide data "as-a-service" with measured and tracked SLAs and costs – whether these services are provided on container platforms or otherwise. Public cloud platforms have made it easy for consumers to leverage SaaS data warehousing solutions. Using DevOps practices do not have to be limited to providing the underlying infrastructure or service, but can also be applied to the building of reports. Jenkins automation can be used to release database updates, integration tools can be used to fetch the relevant data from multiple sources to populate the target systems, and opensource tools like Grafana can be used for dashboards. Primary objective of such a setup would be to capture data from various components and locations within the environment to a centralized location via ETL, and process that data to produce business intelligence. When bringing data in from multiple sources for data warehousing, the exercise of data mapping and data reconciliation and sanitization usually take the most time and effort upfront. Architectural considerations also include the paradigm of monitoring the data warehouse components, as well as the data within it. Data processing engines like Hadoop MapReduce or Spark, along with the database serving platforms form the core components of any data warehouse setup. By implementing the best practices architecture, and tuning specifically for your environment, you can optimize your data warehouse setup to achieve a balance between performance and cost. Various industry use cases like fraud prevention in banking, storing health records and doctors notes in healthcare, customer profiling for retail, real time streaming in media, and others, have already leveraged the benefits provided by data lakes for capturing and storing unstructured data, and data warehousing for structured data. With the adoption of blockchain technologies, the relevance of Big Data is only anticipated to grow. Most enterprises depend heavily on applications for their business, and thereby have adopted agile processes for application releases. Combining the consumption of Big Data with emphasis on extracting relevant and accurate data at the right time, is paramount for business critical applications. The adoption of DevOps practices and tools for data warehousing within data teams is still in its nascent stage, but is being picked up by more and more data experts every day. If you need assistance with data warehousing to move your disparate data from various sources, or need help assessing the feasibility of a data warehouse platform without substantially affecting your business critical applications, Keyva can help. Associates at Keyva have worked with many different organizations in various verticals to help in data migration and application modernization projects. These include things like creating a data migration factory, creating ETL strategies with data mapping, refactoring existing applications, adding a wrapper over current applications so they can be consumed easily by DevOps processes, modifying existing applications to consume data from SaaS platforms, and more.

/hadoop/hadoop-3.1.1/sbin/start-dfs.shOn the master node, run the dfsadmin report, to validate the availability of datanodes
/hadoop/hadoop-3.1.1/bin/hdfs dfsadmin -reportThe output of this command should show two entries for datanodes - one for hadoop1 and one for hadoop2. The nodes are now set up to handle MapReduce jobs. We will look at two examples. We will use the sample jobs from hadoop-mapreduce-examples-3.1.1.jar file under the share folder. There is a large number of opensource java projects available, which run various kinds of mapreduce jobs. We will run these exercises on the master node. Exercise 1: We will solve a sudoku puzzle using MapReduce. First we will need to create a sudoku directory under root folder in hdfs file system.
/hadoop/hadoop-3.1.1/bin/hdfs dfs -mkdir /sudokuThen create an input file with the sudoku puzzle, under your current directory:
vi solve_this.txtUpdate the file with the below text. Each entry on the same line is separated by a space.

Ansible Tower is a RedHat supported and paid version of AWX, which is open source. We will first enable the required repos:
sudo subscription-manager repos --enable rhel-7-server-ansible-2.6-rpms subscription-manager repos --enable rhel-7-desktop-optional-rpmsYou can install the latest version of ansible using Yum:
yum install ansible(Since we will be installing Ansible Tower on this same machine, it is recommended to use the Yum method to install Ansible). -OR- You can build the RPM package by downloading the latest version of Ansible code from Git. If choosing this method, first we will need to get all the pre-requisite libraries ready (some of these are optional):
yum update yum install python-dev python-pip wget yum install git yum update -y nss curl libcurl yum install rpm-build yum -y install pythonDownload the latest code, and build:
mkdir ansible cd ansible/ git clone https://github.com/ansible/ansible.git systemctl stop firewalld systemctl disable firewalld cd ./ansible/ make rpm rpm -Uvh ./rpm-build/ansible-*.noarch.rpmOnce installed, you can view and modify the default Ansible hosts file at /etc/ansible/hosts You can also verify successful installation using the command:
ansible –-versionNow, we can go ahead and set up Ansible Tower on this machine. We will be using the integrated installation, which installs the GUI, the REST API, and the database – all on the same machine:
mkdir ansible-tower cd ansible-tower/ wget https://releases.ansible.com/ansible-tower/setup-bundle/ansible-tower-setup-bundle-3.4.1-1.el7.tar.gz tar xvzf ansible-tower-setup-bundle-3.4.1-1.el7.tar.gz cd ansible-tower-setup-bundle-3.4.1-1.el7/Tower connects to the PostgreSQL database using password authentication. We will need to create a md5 hash to configure Tower to talk with the database. Replace <CUSTOM-DB-PASSWORD> with a password of your choosing:
python -c 'from hashlib import md5; print("md5" + md5("<CUSTOM-DB-PASSWORD>" + "awx").hexdigest())'Make a note of the hash key generated from this command. We will use it for our next step. We have to now update the inventory file (located within ansible-tower-setup-bundle-3.4.1-1.el7 directory) with the passwords for the database, the hash key generated above, and a custom password of our choosing for rabbit_mq. Find the following lines and update them accordingly. First, for setting the admin password for the console
admin_password='AdminPassword'Next, set the password for database connectivity. Please note, this password should be the same as what you used to replace <CUSTOM-DB-PASSWORD> during the hash key generation step above. Also, we will paste the copied hash key, and set it for the hashed password line
pg_password='password' pg_hashed_password='md5f58b4d5d85dbde46651335d78bb56b8c'And finally, choose a custom password for rabbit_mq
rabbitmq_password='password'We are now ready to run the setup script
./setup.shOnce all the steps are completed successfully, you can verify the Tower installation by going to the URL
https://<MACHINE-IP-OR-FQDN>:443You can use the admin credentials (username: admin, password: admin password as defined in the inventory file) to log in and access the console. You can request a free Ansible Tower license for an evaluation environment of up to 10 nodes, or can purchase a RedHat subscription for larger environments, and some additional logging, management and support features. If you have any questions about the steps documented here, would like more information on the installation procedure, or have any feedback or requests, please let us know at info@keyvatech.com.
Scalability: By splitting down the function of an application in to a microservices, it can be scaled independently of other functions or components. For example, a microservice responsible for managing database connections can scale independently of the web tier, if the db connection pool size is to be increased.
Decoupling: Separating the functions into individual services provides flexibility for design, implementation, and maintenance of those individual services.
Continuous Delivery & Updates: Functional upgrades can be released without affecting other components. Each function or service can have its own release pipeline, list of enhancements, and priority for feature releases.
Error Micro-segmentation: Error in one service will be isolated within that service. Faults will not propagate to other functions as they are modularized and separated. Also, releasing an update to address the issue is quicker and more efficient in this architecture.
Parallel Development & Domain Expertise: Each service can have domain specific experts working on it. In the case of monolithic applications, the entire application stack needs to be updated for feature releases, as well as development is stymied because of complexity and interdependencies.
Reduced Deployment Time: Individual services can be deployed with a focus on function specific features and environments. Development, testing, and pipeline release is for smaller modules rather than the entire application stack. Frequent updates can be made to individual services, and those updates can be deployed in production much faster.
If you need assistance in determining the feasibility of transforming your applications from monolithic to microservices architecture, Keyva can help. Associates at Keyva have worked with many different organizations in various verticals to help in application modernization projects. These include things like refactoring existing applications, adding a wrapper over current applications so they can be consumed easily by DevOps processes, and more.

If you are a medium-sized or large organization which depends on your IT teams to provide you with on-demand infrastructure, and support for your business critical applications; if you are an organization with sprawling thousands of applications and are planning to take the journey, or are already on a path, to cloud-native, you must have faced questions like "where do I start in migrating these applications to a new cloud platform?" Or "Once I've migrated an application on to a cloud platform, how do I make sure my application code updates don't drift away from leveraging the most a cloud platform has to offer?".
Let's take a real world example. An organization that has 1500 Applications, about 80% of which are Commercial-Off-The-Shelf (COTS) apps, and about 20% are custom home-grown. These applications are mostly run on unix-based systems, with some instances run on Windows hosts, and they are looking for assistance on getting started with questions like – how do they decide which applications to move? what changes need to be made to these applications to be compatible with the new platform? what risks and vulnerabilities are associated in not taking any actions on these applications? how long will the effort be to migrate these applications? are these applications even ready to be migrated? and so on.
CAST Software provides organizations the ability to have automated application assessments for an entire portfolio of applications using various programming languages, and profile them based on multiple quality and quantity indicators. Using a combination of an assessment questionnaire and the automated code insights, CAST helps you decide which applications to target migrating first, how code changes affect an application resiliency, identify security vulnerabilities in the existing application code, and much more. CAST also provides the ability for you to export the results of your application assessment without the need to export any source code. This can be done by leveraging CAST API. For the example customer mentioned above with thousands of applications, the process of evaluating their entire portfolio of applications can be easily automated leveraging this function.
Here is an example of how the command line API call would look like, that would export the application metrics without the need to export any source code -
java -jar HighlightAutomation.jar --workingDir "/samples/pathToWorkingDir" --sourceDir "/samples/sourceDir/src/" --skipUpload
Since jar files can be run on Unix and Windows systems alike, the command remains the same for both platforms. You can also use the command wrapper created by Keyva (https://github.com/keyva/casthighlight_wrapper) to run the assessment.
For the aforementioned customer, coupling up the ability to run API commands with their configuration management system or a workflow automation system like Red Hat Ansible, they can scan for source code on their server inventory for all on-premises or cloud based servers, and automatically create an application portfolio assessment report on a scheduled basis.
