Cloud - Private vs. Public vs. Hybrid

Cloud Computing:

Everyone is moving fast to Cloud Computing to make infrastructure or service faster and more easy to maintenance, and automotive the tasks and to provide faster service. Cloud computing serves more scalability and reliable, elastic services to IT Infrastructure. Cloud computing provides everything as services over the internet. It will allow us to access and manage every service over the internet from anywhere. 

Cloud Computing services consider in mainly 3 types:

1. SaaS : Software as a Service
2. PaaS : Platform as a Service
3. IaaS. : Infrastructure as a Service


Cloud computing can geographically divide into 3 types. We all know that cloud computing technology is tree types, there are -

1.Private Cloud
2.Public Cloud
3.Hybrid Cloud


These are the major Cloud Computing Technologies moving fast with Technology.

Private Cloud

Private Cloud also known as an Enterprise Cloud, Private Cloud is own by individuals, and its resides on Own Data center premises or Hosted on vendors Data Center location. This is more secure for our data and information with more secured withing our Network and Firewalls. It will Private Cloud is the best solution for companies who already hosted their Servers in Private Data Centers. It can be controlled by own enterprise in the hosted environment with connected with the private or public network. We can manage our own infrastructure with Private Cloud. But this can be more expensive than Public Cloud. Because we have to manage all the hardware and patching, maintenance.
Private Cloud computing is the best option for large companies who runs the business on R&D, Manufacturing, Supply Chain Management, ERP etc.


Public Cloud

Public Cloud is like shared hosting Cloud provider, who runs space with so many customers or tenants. How much we are using those service they will charge for that. Our data is stored Public Cloud providers Datacenter, and provider is responsible for everything like management and maintenance of Hardware and software used in Datacenters. This is the reason so many companies are moving to Public cloud environment to reduce IT expenses.
There is one problem with the public cloud that is “Data Security” because we don’t control the Public network and security to access the cloud environment. Of course public Cloud provider can take care of all security measurements, but still, everyone thinks security could be lacking a with public cloud access.
Public Cloud is the best choice for mid-range service providers like website hosting, and Customer relationship management, Email, and Human Resource Services.


Hybrid Cloud 
Simply we can say Hybrid Cloud is the combination of two more Cloud Environments or combination of Public and Private Cloud environments, Hybrid Clouds makes share the workload or load balancing between both environments. Hybrid Clouds allow you to secure you critical data in private Cloud environment, and we can store or work noncritical Test/Dev products on Public Cloud environment.

Conclusion: These are the main type of Cloud computing technologies available for Enterprise solutions, choosing of cloud technology of big debate. If a large scale company may choose for private Cloud, and if a small scale company may choose public cloud service for serve better service and cost efficiency matters

Troubleshooting Tomcat using Catalina log

Troubleshooting Tomcat using Catalina log We can get the  catalina  logs in  $CATALINA_HOME/logs Here we'll have a  catalina.out We can see some huge info in that log file. If we want to what exactly happens since the start of tomcat then we need to log that into a new file. By default we have log rotation enabled on this logs. For now let us stop tomcat and nullify the catalina.out file and then start tomcat to have some new info in the catalina.out # service tomcat stop # cd $CATALINA_HOME/logs # :> catalina.out (or) cat /dev/null > catalina.out # ll catalina.out -rw-r----- 1 root root 0 Feb 18 16:19 catalina.out # service tomcat start # ll catalina.out -rw-r----- 1 root root 17341 Feb 18 16:21 catalina.out We can see the log being written after the start of tomcat. Now we can notice the instance giving some information about the starting of tomcat, about the configuration for the startup, path of the servlet instance for which the log is responsible for,

Red Hat Enterprise Virtualization Manager RHEL 7 – Part 2

I have just published  what is RHEV  is the first article to understand RHEV Better. In order to maintain multiple RHEV-Hosts from central place RHEV-Manager is required. RHEV-M will be used as central place to manage all RHEV-Hosts. In this Article We are going to see HowTo Install RHEV-M Red Hat Enterprise Virtualization Manager RHEL 7. Red Hat Enterprise Virtualization Management (RHEV-M) is a virtual management console built on Red Hat Enterprise Linux (RHEL). It interacts with individual RHEV-Hosts using the Virtual Desktop Server Manager (VDSM). A VDSM agent is running on each of the RHEV-H nodes. RHEV-M allows administrators to manage/control number of data centers and their network, compute and storage resources. In addition RHEV-M provides a central repository for storing virtual machines, disks, images and virtual machine snapshots. Install RHEV-M Hardware Requirements Hard Disk Space Minimum 50GB RAM Minimum 4GB – Max 2TB Dual Core or High Processor 1Gbps NIC Ca

RHVH 4.1 Installation Steps for Red Hat Virtualization Host

Red Hat Virtualization Host (RHVH 4.1) is installed using a special build ( Download Link )of Red Hat Enterprise Linux with only the packages required to host virtual machines. It uses an Anaconda installation interface based on the one used by Red Hat Enterprise Linux hosts, and can be updated through the Red Hat Virtualization Manager or via yum. Using the yum command is the only way to install additional packages and have them persist after an upgrade. In this article we are going to see RHVH 4.1 installation RHVH features a Web interface for monitoring the host’s resources and performing administrative tasks. Direct access to RHVH via SSH or console is not supported, so the Cockpit user interface provides a graphical user interface for tasks that are performed before the host is added to the Red Hat Virtualization Manager, such as configuring networking and deploying a self-hosted engine, and can also be used to run terminal commands via the  Tools > Terminal.
