I know its possible to upgrade from one medium M3 Instance type to large M3.
But what about upgrade from medium M3 to Large R3? Is this possible? (they are instance type)
Example I use amazon Route 53
Amazon gives me DNS such as
ns-111.awsdns-36.net
ns-222.awsdns-13.org
ns-333.awsdns-53.co.uk
ns-444.awsdns-20.com
But I want to create my own custom nameserver alias, such as...
ns1.mydomain.com -point to--> ns-111.awsdns-36.net
ns2.mydomain.com -point to--> ns-222.awsdns-13.org
ns3.mydomain.com -point to--> ns-333.awsdns-53.co.uk
ns4.mydomain.com -point to -> ns-444.awsdns-20.com
I would then add these custom name server to my registry.
Is this possible?
I have a one to one NAT on pfsense that assigns a public IP to an internal IP (running a web server).
When I open the public IP from an internal machine, it will not resolve to the internal IP, instead it opens the router web page.
When I open the public IP from outside my LAN it will go through to the internal IP that is running the web server.
Why can't I open the public IP internally?
When I create an EBS storage, If I allocate the size to be 500GB but only end up using 30GB do I need pay for the full 500GB or do I pay for 30GB, because this is what i've used?
Ok so you storage your database on Amazon EBS, when you want to add additional storage,
you will need to
- 1) take a snapshot, then wait forever for it to take the snapshot
- 2) create a new larger volume from the snapshot, and again wait forever for it to create your volume.
- 3) stop your instant
- 4) Detach the old volume, and reattach the new volume.
- 5) start your instant
Isn't there a easier and faster way without downtime?
I want to setup SQL Server mirror on amazon EC2 but I always have to add additional storage and worried when i do this my data might get erased?
1) how many principal servers and mirror servers can you have?
2) How does the sync work? is it always 1 direction? principle to mirror and never mirror to principle?
3) What if you take down the mirror server to add more storage then bring it back up will the new data from the principle be pushed onto the mirror server?
4) If you want to take down the principle server to add more storage, Can you change a mirror server into a principle server?
I have a question about XenServer running on a ISCSI SAN
If my XENSERVER dies, would I still be able to purchase a new server, install XENServer and then load up the existing VM's on the new server which are stored on the ISCSI SAN?
(Will it just load? or will it fail? windows key will become invalid?)
Can I run google email service and my web hosting email service on 1 domain?
domain.com <--- on google service (top level domain)
mailman.domain.com <--- on web hosting service (sub domain)
Is it possible to setup SQL Server mirroring and run it with only 1 server right now, then later add another server later?
p.s I cant afford to do mirroring right now, and don't want reconfigure the primary server all over again later on to do mirroring.
I have a few applications running on 1 server, some applications should only be accessible by internal local user's while other applications can be access by anyone on the internet.
http://www.domain.com/APP1 - access internal user and internet user's http://www.domain.com/APP2 - access internal users only http://www.domain.com/APP3 - access internal users only
How do I configure IIS so that it would block internet user's from accessing some of my applications?
- How many failover clustered nodes can you have?, and
- if you add more and more nodes, is it going to slow down?
Everytime I launch a new large ec2 instance, I get 30GB of storage,
Did I do something wrong? shouldn't i get 850GB?
See instance type http://aws.amazon.com/ec2/instance-types/
Large Instance
7.5 GB memory
4 EC2 Compute Units (2 virtual cores with 2 EC2 Compute Units each)
850 GB instance storage (2×420 GB plus 10 GB root partition)
64-bit platform
I/O Performance: High
API name: m1.large
p.s I launch my instances with AWS Management Console wizard.
I get a new elastic IP, I attach it to an instance, but it doesn't work? I can't ping the IP from my local computer either? Am I missing something here?
- How do I use Amazon Elastic IP?
- When is a new IP assign to an instance? When I turn it off and reboot?
Is it possible to have more than 2 servers? (mirror principle) for multiple cluster?
Our application sends out a lot of email notifications! how can I send out email notification without causing long delays?
(its not a email newsletter, its account notifications)
How long does it take to switch from one VM type to another ? (small to large for example)
If you are using windows VM, will you need to reconfigure your server?
1 Is it a good idea to export a VM from one server and import the VM into a completely different server?
2 Would there be any issues?
3 or is it better to just reinstall and reconfiguration everything on the new server (this is good but its rather time consuming).
1 How do you add storage to your Amazon Ec2 servers? Say you need extra HDD space? or another drive?
2 how much does extra storage cost?
3 can I scale from Small Instance to large instance and not lose any data?
Want to know how many visitors can visit the site running on the server before before the server dies?
What to know how fast the hard drive is performing.
I have two servers
1 x SQL Server 2005 Express and 1 x SQL Server 2008 Enterprise
How can I move/import my database from SQL Server 2005 Express to SQL Server 2008 Enterprise?
(BACKUP SQL SERVER 2005 and RESTORE to SQL Server 2008, would that work?)
