Your company is planning to host a large ecommerce application on the AWS Cloud. One of their major concerns is Internet attacks such as DDos attacks. Which of the following services can help mitigate this concern. Choose 2 answers from the options given below

  • A. A. Cloudfront
  • B. AWS Shield
  • C. C. AWS EC2
  • D. AWS Config

Answer:

A. and B. : One of the first techniques to mitigate DDoS attacks is to minimize the surface area that can be attacked thereby limiting the options for attackers and allowing you to build protections in a single place. We want to ensure that we do not expose our application or resources to ports, protocols or applications from where they do not expect any communication. Thus, minimizing the possible points of attack and letting us concentrate our mitigation efforts. In some cases, you can do this by placing your computation resources behind Content Distribution
Networks (CDNs), Load Balancers and restricting direct Internet traffic to certain parts of your infrastructure
like your database servers. In other cases, you can use firewalls or Access Control Lists (ACLs) to control what traffic reaches your applications.

EC2 instances you use. The use of On-Demand instances frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs. Reference: AWS ec2 pricing on-demand

Therefore, each instance in a subnet in your VPC could be assigned to a different set of security groups. If you don’t specify a particular group at launch time, the instance is automatically assigned to the default security group for the VPC. Reference: VPC Security Groups

    This book brought me to tear. Dr Paul Kalanithi was one of the top resident neurosurgeon in the universe and as he was about to finish his residency, he was diagnosed with lung cancer at age 36. He later died 2 years later. He found the courage and strength to write this book while being terminally ill, and oh boy he wrote it beautifully. He described his life, his battle with cancer, his near death experience, his success and failure as Neurosurgeon resident and husband in an elegant and beautiful way. I STRONGLY RECOMMEND THIS BOOK TO ANYONE who wants a real life description of the intersection of sciences, medicine, literature, near death experience, critical illness, cancer, etc.

  • My American Journey
    by Colin Powell (Author)

    My American Journey “A GREAT AMERICAN SUCCESS STORY . . . AN ENDEARING AND WELL-WRITTEN BOOK.”
    –The New York Times Book Review
    Colin Powell is the embodiment of the American dream. He was born in Harlem to immigrant parents from Jamaica. He knew the rough life of the streets. He overcame a barely average start at school. Then he joined the Army. The rest is history–Vietnam, the Pentagon, Panama, Desert Storm–but a history that until now has been known only on the surface. Here, for the first time, Colin Powell himself tells us how it happened, in a memoir distinguished by a heartfelt love of country and family, warm good humor, and a soldier’s directness.
    MY AMERICAN JOURNEY is the powerful story of a life well lived and well told. It is also a view from the mountaintop of the political landscape of America. At a time when Americans feel disenchanted with their leaders, General Powell’s passionate views on family, personal responsibility, and, in his own words, “the greatness of America and the opportunities it offers” inspire hope and present a blueprint for the future. An utterly absorbing account, it is history with a vision.
    “The stirring, only-in-America story of one determined man’s journey from the South Bronx to directing the mightiest of military forces . . . Fascinating.”–The Washington Post Book World

Readers will gain fresh insights into Buffett’s investment strategies and his thinking on management, philanthropy, public policy, and even parenting.Scores of Buffett books have been written, but none can claim this combination of trust between two friends, the writer’s deep understanding of Buffett’s world, and a long-term perspective.Carol Loomis, 82, is at Editor-At-Large at Fortune magazine, where she has worked since 1954. She has written extensively on Warren Buffett since 1966 and is well known as the business journalist on closest terms with him.
