Masterclass Webinar: AWS S3


Amazon Simple Storage Service (Amazon S3), provides developers and IT teams with secure, durable, highly-scalable object storage. Amazon S3 is easy to use, with a simple web services interface to store and retrieve any amount of data from anywhere on the web. With Amazon S3, you pay only for the storage you actually use. There is no minimum fee and no setup cost.

Amazon S3 can be used alone or together with other AWS services such as Amazon Elastic Compute Cloud (Amazon EC2), Amazon Elastic Block Store (Amazon EBS), and Amazon Glacier, as well as third party storage repositories and gateways. Amazon S3 provides cost-effective object storage for a wide variety of use cases including cloud applications, content distribution, backup and archiving, disaster recovery, and big data analytics.

VMware vCenter SRM: Concepts, Architecture


Disaster Recovery at Half the Cost

Lower the cost disaster recovery by up to 50 percent by reducing the DR footprint through hyper-converged infrastructure that runs on any x86 platform, simplifying protection through VM-centric policy-based replication and decreasing operational expenses through DR automation

One-Click Recovery

Provision and manage storage and replication policies at the virtual machine level. Setup centralized recovery plans in minutes. Enable individual tenants to provision disaster protection through pre-defined policies. Perform fully automated orchestration of site failover, planned migrations and failback with a single click.

Test to Rest

Perform automated testing of recovery plans in an isolated network to avoid impacting production applications. Test recovery plans as frequently as needed without disruption to ensure predictability of recovery time objectives (RTO) and to simplify regulatory compliance

No Apps Left Behind

Expand DR protection to all virtualized applications through flexible, cost-effective vSphere Replication, application-agnostic disaster recovery automation by Site Recovery Manager, support for a broad range of array-based replication products available through all major storage partners and cloud-based disaster recovery services available through the VMware Service Provider ecosystem.

AWS VPC to VPC connections over IPSEC VPN


Learn how to build a secure VPN with security and failover between multiple VPCs using Openswan as a software-based VPN solution. Today, we will be going through how to set up a full-mesh topology (where every region has its own unique connection to all other regions). Openswan is a great choice because first of all it is free to use, and it is quite versatile for different use cases.
Also, if you haven’t had a chance to familiarize yourself with Amazon Web Services (AWS) and VPC, I would highly recommend reading up on it. You may be surprised what it can offer your company!

Below this video we provided, configs, and instruction
http://ift.tt/1DPJt7K

# Install openswan

$ sudo su
$ yum update -y && yum install openswan -y

# Make sure the service start at reboot

$ chkconfig ipsec on

# Turn on ip forwarding and other needed directives

$ vi /etc/sysctl.conf

(make sure the these directives are set like what you see below)

net.ipv4.ip_forward = 1
net.ipv4.conf.all.accept_redirects = 0
net.ipv4.conf.all.send_redirects = 0
net.ipv4.conf.default.send_redirects = 0
net.ipv4.conf.eth0.send_redirects = 0
net.ipv4.conf.default.accept_redirects = 0
net.ipv4.conf.eth0.accept_redirects = 0

# save the file and apply the changes

$ sysctl -p /etc/sysctl.conf

# Modify the /etc/ipsec.conf file

$ vim /etc/ipsec.conf

# Below is the template for what you would set in your connection config. Fill in the brackets with your own info

virtual_private=%v4:192.168.0.0/16,%v4:10.0.0.0/8 <---(you can replace these subnets with your own)


conn <CONNECTION NAME>
authby=secret
auto=start
type=tunnel
left=<LOCAL PRIVATE IP>
leftid=<Local PUBLIC IP>
leftsubnet=<LOCAL PRIVATE SUBNET>
right=<REMOTE PUBLIC IP>
rightsubnet=<REMOTE PRIVATE SUBNET>
ike=aes256-sha1;modp2048
phase2=esp
phase2alg=aes256-sha1;modp2048

# Modify the /etc/ipsec.secrets file with the preshared key you want to use between your peers

<Local (LEFT) PUblic IP> <Remote (RIGHT) Public IP>: PSK "mypassword"

example:
54.45.58.87 45.65.128.69: PSK "mypassword"


You can enable PAT/NAT for your private servers that need internet access by using the following command:

iptables --table nat --append POSTROUTING --source <LOCAL PRIVATE VPC CIDR> -j MASQUERADE

Indian Musical League


Thought of writing fictitious event of DMV (Dance, music and voice) then changed my mind. This is because we have so many events on Dance and Voice. Airtel Super Singer, Indian Idol, Bol Baby Bol, etc., called as singing competitions. We don’t know where these musicians are existing. Then there will be local single orchestra doubting there will be fair chance to them. Dance, like there double or triple times of dance programs around in India and telecasted as daily soaps in India. Dance baby dance, Maanada Mayilaada, Dhee, Aata, DID (Dance India Dance). This is the reason I took my step back. Even though the classical forms of singing and dancing are not available, but they are trying to collect all the classical forms to place in these programs.

As far as music, I didn’t find much space here. Doordarshan people started calling it as Boring box, only sold out in Villages. I can able to see that DTH service are available in villages too. But still those who are not having the Set top box and DTH they are enjoying the Doordarshan events. That is the only place I found Indian music alive. Otherwise you know how it goes. What is all about Indian Music league., its an idea which came in my mind. Having the team of music players from the different states with individual performance and team performance which provides fruitful results. Also making these leagues in most of the towns nearly 100 places in India, so that most of them can watch the events. Tiruvayyaar and Tanpur are one of those destinations.

 Even western and our classical rounds can be entered. We can have about 15 teams including North-eastern states. People will started buying the musical instruments, in universities, musical subject will be flourished. So many gurus and sishyas will be created. Gurukuls might be started. Many Grammies came for India. Oscars every season has one nominee from India. This event will goes for 6 months and the finals on December. Karnataka dedicate their music to Basavanna, Tamil nadu dedicate their music for Thyagaraja, Andhra goes for Annamayya, Kerala found Chenda melam as its iconic instrument. Assam came with Dhol, rarest Saringa is for Tripura.

Mridangam, Veena, Sitar, Violin, Tabla and Flute become common musical instruments of all. Piano, Violin, Guitar and Drums are become basic instruments of western musical.

How to Setup Amazon Web Services EC2 Instance



How to Setup Amazon Web Services EC2 Instance with Apache, PHP, MySQL

Instructions:
Go to http://aws.amazon.com/ and create a new account if you do not have an account already.
A credit card or debit is required.

Sign into your AWS account under console management.

Select EC2 and create a new instance.

Choose one of the Ubuntu AMIs, and leave everything default. Under Security groups, create a new security group with SSH and HTTP.
Name your key and download.

Under the terminal, maneuver to the key and chmod 400 to make sure that the permissions are correct.
Under windows, you may have to run as administrator the command prompt or cygwin to chmod properly.
Or you can use the command that I did, which was:
chown :Users testTutorial.pem
Then I did:
chmod 400 testTutorial.pem
Allows only me to read
Then:
ssh -i testTutorial.pem ubuntu@…(public IP)

Once you are on the Ubuntu AMI, you can start to mess around with the packages to install.
I recommend the following: 
Run the command:
sudo apt-get install apache2 libapache2-mod-php5 php5 mysql-server mysql-php5
You can also get phpadmin if you would like.
Remember to restart the apache service:
service apache2 restart

Then, run a secure installation of mysql:
mysql_secure_installation

Go put in your browser the public IP. It works! But what if you want to change the index.html

Well, go cd ../../var/www
In this directory www, you can edit the index.html
sudo vim index.html
You can change the index.html to anything you want using the editor of your choice.

The site changes.
