Common practices for virtual hosting and finding/using error logs and access logs

• Common practices for virtual hosting include using a hypervisor to create and manage virtual machines, setting up virtual networks for communication between VMs, and implementing security measures to protect against unauthorized access.

• To find error logs and access logs, one can typically look in the /var/log directory on Linux systems or the Event Viewer on Windows systems.

• Error logs usually con...read more

To identify if a website is down, check for error messages, try accessing from different devices/networks, use online tools like DownDetector.

• Check for error messages like 'site cannot be reached' or 'server not found'.

• Try accessing the website from different devices or networks to rule out local issues.

• Use online tools like DownDetector or IsItDownRightNow to check if others are experiencing the same issue.

• Check the website's social media accounts or status page for any anno...read more

EC2 is a virtual server in AWS, VPC is a virtual private cloud, CIDR range is a range of IP addresses, security group controls inbound/outbound traffic, load balancer distributes traffic.

• EC2 is a virtual server in AWS that can be easily scaled up or down based on demand.

• VPC is a virtual private cloud that allows you to define a virtual network within AWS.

• CIDR range is a range of IP addresses that defines the network address space for a VPC.

• Security group is a virtual firewall...read more

To address high CPU in a Linux VM, check processes consuming CPU, optimize code, add more resources if needed. To check free memory, use commands like free -h. In AWS, used services like EC2, S3, RDS. Worked on projects involving serverless architecture, data analytics, and automation.

• Identify processes consuming CPU using tools like top or htop

• Optimize code to reduce CPU usage

• Consider adding more resources like CPU or memory if needed

• To check free memory, use commands like f...read more

VPN is a secure connection between two networks while EC2 is a web service that provides resizable compute capacity in the cloud.

• VPN stands for Virtual Private Network and is used to securely connect two networks over the internet.

• EC2 stands for Elastic Compute Cloud and is a web service that provides resizable compute capacity in the cloud.

• VPN can be used to securely access resources on a remote network while EC2 can be used to run applications and workloads in the cloud.

• VPN...read more

HTTP is a protocol used for transferring data over the internet, while cloud refers to the delivery of computing services over the internet.

• HTTP stands for Hypertext Transfer Protocol and is used for transmitting data on the web

• Cloud computing refers to the delivery of computing services like storage, databases, networking, software, and more over the internet

• Examples of cloud services include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform

Check if a string is a palindrome

• Compare the string with its reverse to check if it is a palindrome

• Ignore spaces and punctuation when checking for palindrome

• Examples: 'racecar' is a palindrome, 'hello' is not a palindrome

Yes, the word can be checked for vowels by iterating through each character and checking if it is a vowel.

• Iterate through each character in the word

• Check if the character is a vowel (a, e, i, o, u)

• Return true if any vowel is found, false otherwise

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.

• The OSI model stands for Open Systems Interconnection model.

• It helps in understanding how different networking protocols work together.

• The seven layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and communicates with the adjacent layers.

• For example, HTTP operates at the ...read more

Port numbers are communication endpoints in a network, allowing multiple applications to use the same network connection.

• Port numbers range from 0 to 65535

• Well-known ports (0-1023) are reserved for specific services (e.g. HTTP uses port 80)

• Registered ports (1024-49151) are assigned by IANA for specific purposes

• Dynamic or private ports (49152-65535) are used for temporary connections

Python code to reverse a string

• Use slicing to reverse the string: str[::-1]

• Alternatively, use the join() and reversed() functions: ''.join(reversed(str))
